Habitat Evaluation (Phase I Survey) — HA can perform these surveys at any time of the year, providing there is no significant snow cover. The U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Com­mission also recommend that the ground not be frozen. HA suggests that you contact us for habitat assessments before April 15, in the event that Phase II surveys are necessary.

Presence/Absence Survey (Phase II Survey) — If potential habitat is pres­ent on a property, the U.S. Fish and Wildlife Service and the Pennsylvania Fish and Boat Commission will require that a Phase II survey be conducted before any clearing or development begins. This type of survey is intended to determine whether bog turtles live on the property in question. These surveys can only be conducted between April 15 and June 15 due to the seasonal activity of the bog turtle. See the full list of Guidelines for Bog Turtle Surveys .

Trapping Survey (Phase III Survey) — HA has conducted numerous live-trapping studies for bog turtles, and we are recognized by the U.S. Fish and Wildlife Service and Pennsylvania Fish and Boat Commission as qualified trappers. Trapping is performed as an additional method for determining the presence or absence of this secre­tive species. HA recommends trapping for certain types of wetlands, or when Phase II surveys are initi­ated late in the survey window. When conducted in conjunction with a Phase II survey, trapping increases the likelihood of capturing a bog turtle. Conversely, when no turtles are caught, the use of this method increases the confi­dence that no turtles are present, and ensures that projects are approved in a timely fashion.

Timber Rattlesnake Surveys

The timber rattlesnake is considered a Candidate species, indicating that it is proposed for inclusion on Pennsylvania’s list of Threatened and Endangered species. It is currently listed as a Threatened species by the New York De­partment of Conservation and as an Endangered species by the New Jersey Department of Environmental Protection. Although not officially listed as Threatened or Endangered in Pennsylvania, its status as a candidate for listing still affords it a level of protection under state regulation. Any project con­ducted within the known range of the timber rattlesnake in Pennsylvania must first demonstrate that adverse impacts to crit­ical habitat will be avoided. Critical habitat is defined as overwintering habitat and birthing areas, although other habitat is also considered in habitat assessments. HA has extensive ex­perience surveying, capturing, and handling this venomous, but docile snake. See the current Timber Rattlesnake Presence-Absence Survey Guidelines .

Redbelly Turtle Surveys

The redbelly turtle (also known as the red-bellied turtle) is one of Pennsyl­vania’s largest freshwater turtles, and also one of its rarest. It is currently listed as a Threatened species in Pennsylvania. Potential habitats for this turtle in­clude ponds, lakes, and rivers. The survey period is generally restricted to April 15–July 1 due to the seasonal activity of this species. HA is qualified to conduct assessments of aquatic and nesting habitat, presence/absence surveys, and trap­ping surveys. HA custom builds all of our redbelly turtle traps, which include several design modifications. These have been tested in a variety of habitats, and have been used in a study for the U.S. Fish and Wildlife Service. Our work has included the original population studies at the Philadelphia International Airport, which helped produce mitigation and management recommendations as part of the airport expansion project.

Southern Leopard Frog and New Jersey Chorus Frog Surveys

The southern leopard frog (also known as the Coastal Plain leopard frog) and the New Jersey chorus frog are both listed as Endangered species in Penn­sylvania. New Jersey chorus frogs can be found in densely vegetated wetlands or open marshes, often breeding in temporary bodies of water. Southern leop­ard frogs may inhabit marshes, ponds, and slow-moving streams. Both species are re­stricted to extreme eastern Pennsylvania, generally within the Coastal Plain. These frogs become active with the first signs of spring, and surveys are timed to correspond with their choruses of breeding calls. Surveys should be conducted between mid-March and mid-April. HA has extensive experience with these spe­cies, both in New Jersey and Pennsylvania, and is qualified to conduct surveys for potential habitat (Phase I survey), the presence/absence of the frogs (Phase II survey), and the delineation of critical habitat.
