Calhoun. http://www.fs.fed.us/pnw/publications/scifi.shtml. 1998. They serve as important habitat in the life cycles of several obligate and facultative vernal pool species. As ecological landscaping professionals, it would be a positive volunteer conservation effort to consult with residents and the proper officials to do this. Occasional drying prevents fish from establishing permanent populations, which is critical to the reproductive success of many amphibian and invertebrate species that rely on breeding habitats free of fish predators. 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. "Wetlands" include vegetated wetlands bordering on water bodies, areas within 200 feet of a river (25 feet in certain urban areas), and lands subject to flooding. 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. Exotic invasive woody shrubs could create a more competitive environment for vernal pool specific native vegetation. 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). Based on research at the University of Maine, the Vernal Pools 4-H Science Toolkit includes activities that take youth from learning about biodiversity, to recognizing what a vernal pool is and how scientists determine if a pool is significant. Some examples of facultative vernal pool species include the Red-spotted Newt (Notophthalmus viridescens), American Toad (Bufo species), Spring Peeper (Hyla crucifer), Fingernail Clams (Sphaerium species), etc. These areas may be protected, however, under local wetlands bylaws. Reader’s note: for a more in depth description of vernal pool organisms, their biology, interrelationships, natural threats and threats caused by humans the reader is referred to Colburn (2004). Without predatory fish, the pools are ideal nurseries for developing eggs and aquatic young of frogs and salamanders. The removal of organic matter and shade-casting trees is also problematic (Harris, Clark and Matheny, 2004). 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). 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. Consequences of High Soil Temperatures, pp 27 – 35. Graves, W. R. 1998. 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). Participate in our citizen-based program to document the location of vernal pools. John Engwer, ecological restorationist and developer of the FilterMitt, Use non-chemical means for invasive removal. “Vernal pools are not very common so it is important to protect the ones that we find and make sure they are not destroyed because many animals call vernal pools home and if … 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. A suggested list of disturbances to keep in mind to protect the vernal pool from include dumping green waste, soil, household trash, and garbage; collection of plant and vernal pool organisms; campfires and other camping activities, use of Overland Recreational Vehicles (ORV); dog walking; cutting down trees and brush; and removing rocks, leaf litter, and woody debris (MCCS, 2014; Hammitt and Cole, 1987; Colburn, 2004). 02345. www.manomet.org [Accessed March 25, 2014]. Vernal pools are small bodies of shallow water that contain no fish. Hammitt, W. E., and D. N. Cole. These pools can be located also by listening for an indicator species such as the Wood Frog. These soil and vegetation problems contribute to poor growth of existing landscape plants and increase the potential for siltation runoff toward vernal pool areas from lawn and garden irrigation and rain events. The following strategies can help with management of soil compaction on new construction sites. The rules provide definitions of vernal pool, primary vernal pool indicators and secondary vernal pool indicators. Then, the developers can take this into account when they are drafting their plans, and conservation commissions can e… 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 ~ … Microarthropods are part of the decomposer community and serve as food for vernal pool amphibians in the life zone. Issue 136. Colburn, E.A. In fact, according to some estimates, over 90% of the vernal pool habitat in 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. On the other hand, obligate vernal pool species are dependent on using the pool. by Bruce Wenning There are many types of wetlands in our environment, but all of them are declining. Massachusetts Audubon Society, Lincoln, MA. 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, The Grosses are forward thinking private landowners in Lycoming County who explored different conservation options to protect their vernal pools. In Massachusetts, vernal pools are legally recognized only if they have been certified by the Massachusetts Natural Heritage and Endangered Species Vernal Pool Program. If you find a vernal, check with your local conservation commission and/or the Massachusetts Natural Heritage and Endangered Species Vernal Pool Program to determine if the pool has been certified or, if not, how you and your client can certify it. Seventh edition, Winter 1997. Manomet Center for Conservation Sciences, 81 Stage Point Road, Manomet, Mass. Coir products used for erosion control are the best for wetland protection and can be applied to vernal pool protection strategies when and where applicable. (Colburn, 2004). How to Protect a Vernal Pool • Identify a buffer zone around your vernal pool– preferably not harvesting trees within 100 feet of the pool, and using a light touch (retaining 85% canopy cover, creating minimal ground impact, and leaving downed wood) within 300 feet • Maintain at least 2 fallen trees per acre, as well as standing dead trees around the pool must protect our vernal pools. Prentice Hall, Upper Saddle River, N. J. In Westborough, which has 42 official vernal pools, a lot of people took it upon themselves to have them certified, said Plagge. There are efforts being made to protect the vernal pools that still exist as their disappearance could also mean the disappearance of important plant and animal species. An Environmental Vision. Science and Conservation of Vernal Pools in Northeastern North America. Taking away or degrading valuable uplands from these obligate species is like taking away oak trees from squirrels or milkweed plants from monarch butterflies. Salamanders of the United States and Canada. In Watson, G. W., and D. Neely (Eds). Massachusetts is unique in its efforts to protect vernal pools. Vernal Pools: Natural History and Conservation.
