How You Can Help Fill-in Data Gaps

YOUR WILDLIFE SIGHTINGS CAN HELP INFORM NEW JERSEY’S BIOLOGISTS

By Michael Davenport, GIS Program Manager

Compared with most of the states within the United States, New Jersey is relatively small in area. However, it is still too large for biologists within New Jersey’s Endangered and Nongame Species Program (ENSP) to survey every inch of the state for rare species at all times. Therefore, ENSP has created a Rare Wildlife Sighting Report Form with which any bird watcher, hiker, fisherman, and anyone else with knowledge on how to identify New Jersey’s rare wildlife, may submit information on rare species which they may have come across in their travels. This information assists ENSP biologists in monitoring their species’ numbers and whereabouts and may aid in targeting areas for future surveys. Conserve Wildlife Foundation of New Jersey (CWF) staff work very closely with ENSP to encourage the public to submit their observational data and then process the information which gets submitted.

The first step in reporting rare species sightings is to first determine whether the species you observed is a species which is tracked. Tracked species are those listed in New Jersey as endangered, threatened, or special concern. The lists of these species can be found on these ENSP’s websites:  endangered & threatened species and special concern species.

The greatest need for data is for those species which are new to the proposed list of endangered, threatened, or special concern species. Because they did NOT previously have an imperiled status, they have largely been ignored in terms of survey effort and/or data acquisition. At the current time, there is a great need for data regarding observations of the following species:

Reptiles

Amphibians

Butterflies

Once you have determined that you observed a rare species, the next step is to complete a Rare Wildlife Sighting Report Form. You may complete one of these forms if you made the observation yourself – second-hand observations or information whose source was a report, letter, conversation, or other document will not be accepted. Also, one form must be completed per species. Thus, if you observe a heron rookery comprised of great blue herons, tricolor herons, and snowy egrets, then three sighting report forms may be submitted.

Rare Wildlife Sighting Report Forms are available for download and/or printing here. Part of the process of completing the form is to submit a map of the location where the animal was observed. This is critically important for reasons to be discussed later. The preferred map to submit is an aerial image of the area which you have marked with the animal’s location; however, a topographic map is also acceptable. Aerial images may be accessed via Google maps. Topographic maps can be accessed here. In addition to the form and map, it is also extremely helpful if you can submit at least one photograph of the animal in order for an ENSP biologist to verify the identification of the species.

After you mail in your form and map to ENSP, CWF or ENSP staff will enter it into their tracking database at which point it will receive an Observation ID number. You will then receive an e-mail acknowledging receipt of your form and providing you with your Observation ID number in the event you wish to follow-up with additional information or inquire as to whether the biologist has reviewed your form.

The form then goes to a CWF or ENSP biologist who will evaluate it to determine whether it is a valid sighting and whether it should be integrated into the next version of ENSP’s Landscape Project. This is why receiving accurate locational information along with the sighting report form is crucial. The Landscape Project is a Geographic Information Systems (GIS) product whereby critical areas are identified for imperiled species based upon species locations as well as land-use classifications. The resulting maps enable state, county, municipal, and private agencies to identify important habitats and protect them in a variety of ways. This information is even utilized to regulate land-use in the state and attempt to preserve whatever endangered and threatened species habitat remains in New Jersey.

A common misperception many New Jersey nature watchers have is, if they happen to report their rare species sightings to institutions such as Audubon or Cornell (e-bird), that information will make its way to the state’s Endangered and Nongame Species Program. That is not the case. ENSP needs you to submit your data directly to them. So, please, become a Citizen Scientist and assist both CWF and ENSP in tracking New Jersey’s rare species, in the hopes that our work can prevent them from becoming rarer.

If you have collected a large amount of data and submitting it via multiple Sighting Report Forms may be too time consuming, please contact Mike Davenport, CWF’s GIS Program Manager, at Michael.davenport@dep.nj.gov Other options exist for data submittal (Excel spreadsheets for example) so long as all of the required information is included.

Providing Young Forest Habitat for the Golden-winged Warbler

CWF and partners have created or restored over 225 acres of Golden-winged warbler habitat in New Jersey since 2012

Take a look at this Golden-winged warbler — a Neotropical Migrant songbird that breeds in New Jersey. This songbird is a species of special conservation concern in the United States and endangered in New Jersey, experiencing population declines due to loss of young forest habitat.

 
Did you know? In the past 30 years, over 11,000 acres of upland shrub and emergent wetland habitat have been lost to succession in New Jersey. This habitat is important for Golden-winged warblers because it is their primary breeding habitat. Fortunately, their secondary habitat, upland forests, have remained stable in the state.

 

Therefore, it has been the goal of many wildlife management agencies to continue to create young forest habitat, while protecting upland forests as well.

 
Conserve Wildlife Foundation and our partners (Natural Resources Conservation Service, New Jersey Division of Fish and Wildlife and New Jersey Audubon Society), have worked with private landowners to create or restore over 225 acres of Golden-winged warbler habitat since 2012 in New Jersey.

 

Our managed forests have a statistically significant higher diversity of birds than unmanaged sites!

Young forest habitat, also known as scrub-shrub habitat, is new or regenerating forest that is less than 20 years old. Young forest habitat is important for many birds, especially the Golden-winged warbler. The open canopy of a young forest also helps provide food such as berries and insects to newly fledged birds, wild turkey, ruffed grouse, reptiles, black bears, bobcats, and butterflies.

The breeding range of the Golden-winged warbler extends along the Appalachians from the northern portion of Georgia in the south to Vermont in the north. The winter range for this species is southern Mexico and Central and South America.
