Functions and Values Vernal pools have benefits to society and the environment. * Flood control * Water purification * Habitat for animals * Beautiful to explore Threats Vernal pools are sensitive to human harm. Habitat Loss Agriculture, construction, logging, and quarries cause a loss of habitat. Changing Hydrology Developments may decrease the water table. Pools may be dug deeper for a permanent fish pond. Water Quality Runoff contains sediment, salt, oil, and chemicals that harm pool life. Climate Change Temperature changes and rainfall amounts may affect animal life cycles. Helping Hand Here are steps to protect vernal pools. * Allow a buffer; avoid mowing too close * Avoid cutting trees around the pool * Limit pesticides and herbicides * Do not dig a temporary pool deeper * Conserve water Pennsylvania Vernal Pool Registry This registry allows volunteers to submit information on vernal pools. www.naturalheritage.state.pa.us/ VernalPool_Register.aspx Pennsylvania Amphibian and Reptiles Survey (PARS) This statewide atlas helps us understand where herps live. Citizens can report observations or join as a volunteer. https://paherpsurvey.org Become a Superhero Check out the Pennsylvania Angler & Boater July/August 2020 PLAY " Superheroes of Summer " to learn how to help and become a Citizen Scientist. Habitat Fragmentation Construction and agriculture breaking up the landscape, animals killed crossing roads, and invasive species outcompeting native species in open areas are examples of habitat fragmentation. Vegetation Changes Logging reduces shade, increasing water temperature. Vegetation removal eliminates egg sites and cover. 52 Pennsylvania Angler & Boater * January/February 2021 www.fishandboat.comhttp://www.naturalheritage.state.pa.us/VernalPool_Register.aspx http://www.naturalheritage.state.pa.us/VernalPool_Register.aspx https://www.paherpsurvey.org http://www.fishandboat.com
