how to protect vernal pools

International Society of Arboriculture, Champaign, Illinois. Subscribe to our e-news for the latest events, updates and info. 1987. Salamanders of the United States and Canada. Direct and indirect effects of trampling on soil and vegetation include 1) collapse of abandoned rodent burrows that kills hiding amphibians; 2) increased risk of pool siltation and water carrying pollutants; 3) increased risk of lawn/garden weed invasion; 4) increased risk of plant root and stem pathogen entry causing disease; and 5) opening life zone and pool canopy increases sun exposure that favors an influx of invasive woody plants and lawn and garden weeds; increases soil temperatures, favoring drought conditions at times; and causes amphibian microhabitat alteration. Use Pervious Parking Lot and Foot Path Products: There are specialized water pervious paving compounds made of concrete or rubber that are designed to intercept precipitation into the ground and support vehicle and/or pedestrian foot traffic at the same time. Betsy currently is the aquatic ecologist at the Harvard Forest, Petersham, MA. We serve an important role of officially certifying vernal pools that are documented by citizens, researchers, and other parties. Root Growth Control: Managing Perceptions and Realities, pp 51 – 81. Then, the developers can take this into account when they are drafting their plans, and conservation commissions can ensure maximal protection for the vernal pools through the permit ("Notice of Intent") review process. This created soil type could help reduce soil erosion and polluted runoff towards vernal pools and associated life zones. They are often overlooked when wetlands are identified on development sites because in many months these areas are dry and resemble the surrounding woodland. Scientists first recognized vernal pools as ecosystems in the 1930s, but it took years to understand that they were breeding destinations for native crustaceans, such as fairy shrimp and hyperlocal salamander and frog species. However, alterations and destruction of wetlands may be allowed under various regulatory provisions. Then find out how the built environment affects vernal pools and what you can do to minimize disruption and damage. Woodland pools provide critical breeding habitat for a number of amphibians and invertebrates that have adapted to their unique conditions. Why is the protection of vernal pools important? In fact, according to some estimates, over 90% of the vernal pool habitat in Petranka, J. W. 1998. Table 1, illustrates some of the major ecological or life history needs determined to be essential for the aquatic reproductive phase and associated land-dwelling phase for obligate vernal pool species. Certification efforts should occur well in advance of a development proposal in order to be most effective. In Massachusetts, vernal pools are legally recognized only if they have been certified by the Massachusetts Natural Heritage and Endangered Species Vernal Pool Program. Vernal pools or "spring pools" are shallow depressions that usually contain water for only part of the year. These biologically unique, fishless water bodies are found in many types of woodlands and forests throughout the glaciated northeast (Colburn, 2004). Schematic drawing of a hypothetical Vernal Pool : Built Environment Interface. Vernal pools generally hold water for several months in the spring and early summer and are often dry by fall. When soil compaction precautions are not deployed, soil erosion increases from the impervious areas towards or in vernal pool life zones. In this case, the life zone includes the minimum area necessary for protection and maturation of obligate vernal pool amphibian juveniles and adults (Colburn, 2004) and includes the vernal pool. Wildland Recreation: Ecology and Management. Certification also protects vernal pools through the federal Clean Water Act and the associated state Water Quality Certification Program. The Landscape Below Ground II: Proceedings of an International Workshop on Tree Root Development in Urban Soils. Keep out! Amphibians are excellent biological indicators of environmental stress and their declining populations can be partially attributed to various land use changes affecting their survival ecology. 1 While this is helpful for overall water quality, it does not encompass the vast terrain where vernal pools should exist. Arboriculture: Integrated Management of Landscape Trees, Shrubs, and Vines (4th edition). When rain fills the pools in the winter and spring, the water collects and remains in the depressions. Colburn, E. A. The vernal pools serve as essential breeding habitat for certain species of wildlife, including salamanders and frogs (amphibians). If you think your property contains a vernal pond, you can do a lot to protect it from potentially harmful effects of land use. This is why upland life, which is measured in years, is as important to life cycle completion for these obligate animals as the breeding (natal) pool. Vernal pools are defined as “seasonal, semi-permanent or permanent bodies of water that are essential breeding habitat for certain amphibians and invertebrates and do not support fish” (Hunter, Calhoun, & McCollough, 1999). With macropore collapse or reduction the resulting soil eventually gets filled with water, depleting available soil oxygen which limits plant root growth. (Calhoun and Klemons, 2002). Strategies to Protect Vernal Pools in the Built Environment: Raising Awareness - Ecological Landscape Alliance. Built environment land use and maintenance activities contribute greatly to vernal pool life zone threats like soil erosion, runoff, and pool sedimentation. Vernal Pools. Mole salamanders will migrate to forested uplands that are 1,000 feet from their breeding pools. As ecological landscaping professionals, it would be a positive volunteer conservation effort to consult with residents and the proper officials to do this. All soil compaction contributes to water running over the hardened soil and washing away adjacent non-compacted soils. All Rights Reserved. In Watson, G. W., and D. Neely (Eds). Best Management Practices for Conservation of Pool – breeding Amphibians in Residential and Commercial Developments in the Northeastern U. S. Technical Paper No. Perry, T. O. These pools can be located also by listening for an indicator species such as the Wood Frog. Certification is one of the best ways to protect vernal pools, which are extremely vulnerable to development. The more trails created, the more fragmentation occurs. CRC Press, Taylor and Francis Group, Boca Raton, FL. If you are a private property owner who owns woodlands than you need to first determine if your property includes vernal pools. Get in the woodland and walk around. Certain tropical fish lineages … The eggs hatch and their larvae or tadpoles develop over the Soils on building and road construction sites are highly compacted to strengthen the soil for providing a stable building and road site base and are not designed for growing landscape plants (Harris et al, 2004: Craul, 1994; Randrup, 1998; Coder, 1998). Your design goals and decisions, as well as the land management practices that you provide for your client can allow you to be a direct contributor to vernal pool conservation on that property and in that community. What is a vernal pool, and why should Maine people care about protecting them? The Landscape Below Ground II: Proceedings of an International Workshop on Tree Root Development in Urban Soils. Legislation needs to be more aggressive at embracing and instituting specific science based reasons for strengthening wetland protection laws beyond what currently exists in most states, particularly for vernal pools which are largely overlooked by the general population (Colburn, 2004). URI students study vernal pools to help protect amphibians Media Contact: URI Communications , 401-874-2116 | Share: Twitter Facebook KINGSTON, R.I. — October 2, 2001 — One key to the survival of frogs, salamanders and other amphibians is the hydrology of vernal pools, the small woodland ponds that dry up for part of each year. info@phaseIIstormwaterproducts.com, 508-384-1984, SumCo ECO-CONTRACTING, Salem, Mass. Local bylaws can also increase the amount of protection for buffer areas around vernal pools, compared to the limited buffer zone protections provided through state law. Define Use Zones: For new construction projects, developing an inventory of equipment, worker, and materials storage needs, and any additional resources required before construction begins will help plan for better timing and sequencing of project developments prior to laying out roads, paths, storage areas for heavy equipment and building materials, dividing up building lots and positioning buildings (Perry, 1998). Her text book on vernal pool natural history and conservation is listed above in the Literature Cited. 2004. Calhoun, A. J. K., and M. W. Klemons. … 2002. URI students study vernal pools to help protect amphibians Media Contact: URI Communications , 401-874-2116 | Share: Twitter Facebook KINGSTON, R.I. — October 2, 2001 — One key to the survival of frogs, salamanders and other amphibians is the hydrology of vernal pools, the small woodland ponds that dry up for part of each year. For life cycle completion, these amphibians need life zones that include protected (shaded), productive, and undisturbed wooded uplands much larger than the current 100 foot buffer zone provides (Colburn, 2004). The McDonald & Woodward Publishing Company, Blacksburg, Virginia. Pursuant to the Connecticut Inland Wetlands and Watercourses Act the term 'watercourses' includes vernal or intermittent waterbodies. Anyone can file a "Request for Determination of Applicability" with the local conservation commission to find out whether or not an area is a protected wetland. Vernal pools are a severely threatened resource in the state and are only given the highest level of protection under the Massachusetts Wetland Protection Act if certified. Parks, N. 2011. Vernal pools are extremely vulnerable to development. The rules provide definitions of vernal pool, primary vernal pool indicators and secondary vernal pool indicators. The occurrence of glyphosate, atrazine, and other pesticides in vernal pools and adjacent streams in Washington, DC, Maryland, Iowa, and Wyoming, 2005 – 2006. The Landscape Below Ground II: Proceedings of an International Workshop on Tree Root Development in Urban Soils. 1998. Vernal Pools. The surface should be compacted enough to carry light traffic while remaining permeable to air and water. Other pools follow a similar pattern, but fill with rain in autumn, hold water all winter and spring, and then dry out by late summer. 426 pp. 1994. In turn, these plants and animals provide food and habitat for shorebirds and waterfowl. Vernal pools are a very important ecosystem that are increasingly being threatened. The abundance of life associated wi… Use of these products would be particularly beneficial for new housing developments and commercial complexes in vernal pool life zones. Facultative vernal pool species may or may not use the vernal pool for the completion of their life cycles. University of Maine, Sustainability Solutions Initiative, Orono, ME. Signage should be posted with rules for conservation of vernal pool habitat near private property and parking areas. The Landscape Below Ground II: Proceedings of an International Workshop on Tree Root Development in Urban Soils. The Landscape Below Ground II: Proceedings of an International Workshop on Tree Root Development in Urban Soils. 155: 281 – 307. Therefore, under Connecticut law, vernal pools, which contain a specific ecology, are one type of vernal watercourse, and Connecticut's municipal inland wetlands agencies regulate any activities that are likely to impact or affect vernal … Vernal pools are defined as “seasonal, semi-permanent or permanent bodies of water that are essential breeding habitat for certain amphibians and invertebrates and do not support fish” (Hunter, Calhoun, & McCollough, 1999). must protect our vernal pools. Colburn (2004, p. 174) describes an amphibian’s return to the natal (birth) pool as a behavior that shows a “high degree of site fidelity.” Petranka (1998), discussing the Spotted salamander’s breeding behavior states that the natal pool odors (an olfaction characteristic) directs that salamander back to its natal pool for breeding. Of Pools and People University of Maine Researchers and colleagues Receive a National Science Foundation Coupled Natural Human Systems Grant (Orono) Understanding the vital connections between landowner concerns, municipal planning, conservation activities, and the ecology of vernal pools will be the focus of natural and social scientists from the University of Maine, Clark University, Enhancing Wildlife Habitats: A Practical Guide for Forest Landowners. The action of unrestricted foot and vehicle traffic on unprotected woodland life zone ground cover and bare soil areas will undoubtedly lead to widespread soil compaction and plant damage including the collapse of abandoned rodent tunnels and burrows used as homes and hiding places for obligate pool amphibians during their juvenile and adult life cycle stages. Learn why vernal pools are critical habitats for certain species, how to identify them, and how to protect these fragile ecosystems in this EcoBeneficial interview. Any type of life zone habitat destruction will threaten the existence of these secretive creatures. It’s unreasonable to expect that their innate aquatic phase, including their unique reproductive physiology and behaviors coupled with their upland juvenile and adult phase requirements, will change to accommodate current wetland law. Refer to Figure 1. Remember to secure permission from landowners before undertaking exploratory hikes. Learn about the threats to vernal pools and what you can do to help protect them. What can you do to protect vernal pools? Though the fairy shrimp spends its entire life time in the pool, wet and dry, the woodland area surrounding the pool is just as important as the pool for amphibians. Figure 1. When you are requested to remove exotic invasive woody plants from a life zone area, you should pull by hand or wrench plants out of the ground using a puller device. Whether a wetland is a wet meadow, marsh, swamp, forested wetland, bog, lake, pond, river, stream, or vernal pool, these and other more defined wetland types provide habitat for a diversity of plant and animal species: some site specific, some not (Hobson et al, 1993; Colburn, 2004). Certified: A Citizen’s Step-by-Step Guide To Protecting Vernal Pools” is a Mass Audubon publication that guides citizens through the certification process. Learn about the threats to vernal pools and what you can do to help protect them. Nevertheless, construction of new homes and commercial buildings that encroach into vernal pool wetlands result in lost native vegetation, compacted soils, newly installed garden beds and lawns that require maintenance (often with inorganic fertilizers and non-organic pest control chemicals). Maine Amphibians and Reptiles. In the Hudson Valley, these include the mole salamanders, wood frogs, and fairy shrimp (PDF) (950 KB). http://www.fs.fed.us/pnw/publications/scifi.shtml. During construction activities, leaf litter that normally occurs in life zone areas is often partially or completely eliminated for aesthetic appeal and/or weed geotextile barriers are installed in perennial beds to control weed growth. Western vernal pools are also hot spots of biodiversity, with native plant and animal species some of which can only be found in vernal pool habitats. Vernal pools do not contain fish, which are predators to salamander and frog egg masses. Part 1 & Part 2. Raising wetland conservation awareness through education is paramount for understanding the link between the ecological networks and biological processes of wetland plants and animals and the very important need for their continued protection. Vernal pools are something of a Californian oddity–they thrive in Mediterranean climates and California’s pools stand out for their many native species. They are often overlooked when wetlands are identified on development sites because in many months these areas are dry and resemble the surrounding woodland. Seventh edition, Winter 1997. Most of us working in the landscape have come across mixed attitudes concerning wetlands. Additionally, the pool risks becoming deeper and wider resulting in a longer than expected dry down phase which affects the sequence and timing of vernal pool fauna and associated predator-prey relationships (Colburn, 2004). These areas may be protected, however, under local wetlands bylaws. Northeast Regional Agricultural Engineering Service, [NRAES-64] Cooperative Extension, Ithaca, N.Y. 172 pp. The removal of organic matter and shade-casting trees is also problematic (Harris, Clark and Matheny, 2004). As a result, most pools have been converted into residential zones, roads, and industrial parks. Vernal pool species, such as frogs and salamanders, make nests and lay eggs in these pools and strong, unnatural disruptions in the water might kill the eggs or destroy the nests. All of the life zone includes habitat critical to obligate species (Colburn, 2004). Trampling damage can occur rapidly and, if allowed to continue, increases site susceptibility to widespread soil erosion which could lead to vernal pool siltation. 1997. Eggs in a vernal pool. The Award Goes To…. Colburn, E.A. Randrup, T. B. Coder, K. D. 1998. They are considered the “smaller wetlands” in our landscapes. For instance, amphibian species depend on forests for their adult lives and on ponds for breeding and the development of young. You will find a variety of resources on vernal pool ecology, the animals that breed in and use vernal pools, an explanation of state and federal regulations pertaining to vernal pools, and materials developed to assist you with field assessments and local mapping projects. Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals.They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. This involves unorthodox but safe techniques to replenish microhabitat cover and moisture and temperature regimes in an effort to conserve vernal pool amphibians. Third, identify the pool perimeter. First, check for the presence of a vernal pool. Freshwater wetlands are generally defined as areas of transitional ecosystems between upland (terrestrial) and bottomland (aquatic) where water is present for all or part of the growing season (Hobson, Barclay and Broderick, 1993). (Source: modified slightly from Hammitt and Cole, 1987). Vernal pools used to be the most common kind of wetland in Ohio, but there are not nearly as many of them as there used to be. Obligate vernal pool species evolved over time to take advantage of fish-devoid, temporary waters and undisturbed uplands that were much more numerous in the landscape when the Pilgrims landed than they are now. These important and diverse aquatic and semi-aquatic life forms depend directly on the local and regional hydrology (the movement of water in relation to land) where wetlands occur. If you are working on a property that has adjacent woodlands, check that area in spring for vernal pool water bodies. Years ago, I heard home builders and land developers disparage wetlands as a “mosquito nuisance” or “wasteland” or “cheap land that could be developed.” Now, more people view wetlands as components of the local and regional ecosystem with the general consensus being that wetlands are important and “should not be disturbed.” Attitudes are changing, but the United States is still losing valuable wetlands at an alarming rate! As was mentioned in a Jan. 19 Press Herald article by Tom Bell (“LePage: Ease regulations that protect vernal pools”), vernal pools are “small bodies of water that dry up for part of the year. To Protect Vernal Pools, You Have to Find Them First. Multiple trail use or creation should be discouraged. A database of vernal pools in Pennsylvania. International Society of Arboriculture, Champaign, Illinois. This field is for validation purposes and should be left unchanged. Bronx, N. Y.: Metropolitan Conservation Alliance. Vernal pools dry completely by the middle or end of summer each year, or at least every few years. Vernal pools are depressions in areas where a hard underground layer prevents rainwater from draining downward into the subsoils. Although the NJ Freshwater Wetlands Protection Act has been in place since 1989, it has done little to protect vernal pools because wetlands smaller than 1 acre (many vernal pools in NJ are ~ 0.25 acre) are exempt from the regulatory protection. Without proper certification, the vernal pool has little, if any, legal rights of protection from building development and other major land use changes. Soil compaction and vegetation trampling are major issues caused by human recreational and landscape maintenance activities in vernal pool life zones. restored pools in a way that mimics natural vernal pool complex topography/hydrology; f) A hydraulic analysis that shows each proposed vernal pool and its watershed, the vernal pool to watershed ratio, and hydrologic connection between the pools. 2004. He describes using three zones on work sites with the goal of restricting building activities that cause soil compaction to specific areas: The use of appropriate signage and fencing helps with designating these zones. Their temporary nature precludes supporting fish. What is a vernal pool, and why should Maine people care about protecting them? By the late 1940s, wetland acreage dropped to 45 million acres and by the 1980s an annual loss of 300,000 acres was reported (Hobson et al, 1993). Harris, R. W., J. R. Clark, and N. P. Matheny. Vernal pools are wetlands with a seasonal cycle of flooding and drying. During that time Bruce occasionally worked for Betsy Colburn, Mass Audubon’s aquatic ecologist, assisting her and her staff with vernal pool insect identification and some field work. Identify and document vernal pools with the Ashuelot Valley Environmental Observatory, the citizen science arm of the Harris Center for Conservation Education. Here’s how: The timing of certification efforts is critical. What most people don’t know or understand is that many existing vernal pools have lost much of their important surrounding woodland or upland areas, often referred to as life zones, which are essential for pool amphibian life cycle completion. The best time for removal would be from November to February, and work on only a small area each year so as to, Increase shade within the life zone. Vernal pools are a severely threatened resource in the state and are only given the highest level of protection under the Massachusetts Wetland Protection Act if certified.
