Conserve Wildlife Foundation is excited to release Pollinators in Peril, the third episode of ‘State of Change’, our podcast exploring the impacts of climate change on New Jersey’s wildlife.
A new pollinator habitat is created in Middle Township
By: Larissa Smith; CWF Wildlife Biologist
The Middle Township Environmental Commission in cooperation with the Conserve Wildlife Foundation of NJ worked to create a pollinator habitat at a recreation site in the township which is located in Cape May County. Commission members had been working to obtain permission to plant a pollinator garden on a township site. The Ockie Wisting Recreation Complex was just officially opened in the end of October. This recreation site will have playing fields, a playground and a wooded trail that leads to a lake and fishing pier.
With funding from Atlantic City Electric volunteers with the Middle Township Environmental Commission and Conserve Wildlife Foundation of NJ planted 138 native perennials . While it doesn’t look like much right now, come next spring and summer there will be plants for bees, butterflies and birds to use for food and habitat. Not only will this pollinator meadow be great for wildlife, it won’t have to be mowed. The Environmental Commission will be in charge of maintenance and plans another work day in the spring to remove any non-native plants and trees in the area. We also plan to use this site as a demonstration garden for others interested in planting for pollinators.

Monarch has been a conservation buzz-word for the past decade when data revealed that the population had appeared to be on the decline. Then in 2013, the population of wintering monarch butterflies in Mexico reached an all-time low that jolted scientists, environmentalists, and enthusiasts across the nation.
Monarch abundance in wintering grounds is measured as area in hectares. They roost in large colonies in the Transvolcanic Mountains in Mexico. The 2013-2014 overwintering population experienced the lowest recorded area to date, at 0.67 ha. From MonarchWatch.org.
This marvelous and iconic lepidopteran is found throughout the continental United States. Its 3,000 mile long migration is an amazing natural phenomenon. The news of population declines in Mexican wintering sites inflamed concern and incited action. Many groups have since created partnerships, implemented programs, and conducted research to understand more about this widely known yet still mysterious insect.
The location of wintering monarchs was a complete mystery until 1975 when the remote wintering sites were discovered in transvolcanic mountain ranges in Mexico. Much is still to be discovered about the migration pathways even within the United States, and doing so will answer questions which will inform conservation and management of this species which faces multiple threats during every aspect of its expansive journey.
Glider pilots have observed monarch butterflies at an altitude of 1200 meters (Gibo 1981). Migratory flights at these altitudes can allow insects to disperse against wind directions found at lower altitudes.
But first, a little bit about biology and the annual life cycle
The monarch’s annual lifecycle is a really marvelous and multifaceted journey – it can be thought of as a multigenerational relay race.
From the Xerces Society. Map depicts the known general migration routes of monarch butterflies.
Monarch butterflies, just like other lepidopterans, metamorphosis from caterpillar to butterfly. The big thing that sets them apart is the migration they make annually. (Although there are many other species of moths and butterflies, and other insects as well that migrate – the monarch is arguably the most well recognized example http://texasento.net/migration.htm).
Temporal cues and an innate determination drive these ambitions fliers to travel as far north as the Canadian border. In the search for milkweed and favorable temperatures – possibly to avoid disease pressures – monarchs fly north to reproduce and recolonize across North America each year.
They leave overwintering grounds in Mexico in early spring. Along their route the monarchs will mate and reproduce. Their lives are lived within a short couple weeks, and their offspring will continue the migration northwards in search of food and milkweed.
When the seasons shift in late summer and early fall, the last generation of monarchs will begin a southbound journey, instinctively traveling to wintering sites in Mexico (there are a few populations that overwinter in California and Florida – but the large majority are thought to return to Mexico). This generation will be responsible for making the longest trek of the migration to wintering grounds. These monarchs enter reproductive diapause – the state where the body will temporarily pause reproduction – until the following spring. These monarchs will spend the winter roosting in trees in Mexico until spring when they will take up the first leg of the relay north.
This last generation from the previous year now makes up the first generation of the present year – and will pass the baton on to their offspring as the cycle starts anew.
The role of the Garden State
So what part does New Jersey play in the grand scheme of this massive population?
The Atlantic coast migration was once characterized as “aberrant”, a fluke of sorts – the result of southbound monarchs being blown off course. Research and monitoring conducted in Cape May and published by Walton and Brower (1996) in The Journal of the Lepidopterist’s Society have supported the hypothesis that a migration along the Atlantic coast is part of the monarch’s normal fall migration.
What does a monarch have in common with a hawk?
Walton and Brower (1996) have proposed the idea that monarch butterflies could display similar flight patterns to that of migrating hawks. Utilizing an elliptical flight path during the fall south-bound migration, the model suggests that these birds take advantage of prevailing winds by first traveling east and then west, thus providing a quicker and more energetically-efficient route. Could monarch do the same?
New Jersey – Southern New Jersey and Cape May in particular – is historically recognized as a concentration area for southbound monarchs during the fall migration to wintering grounds. Hamilton (1885) [expressed his wonder of the] characterized the September 1885 monarch migration at Brigantine, New Jersey as “almost past belief … millions is but feebly expressive … miles of them is no exaggeration.” Reports of trees “more orange than green” is no exaggeration, as monarchs congregate en masse in prime roosting spots to warm and rest.
But why is this important? The monarchs migrating through Cape May seem to be representative of the entire North Eastern population – and therefore it offers the opportunity to collect quantitative data on populations in addition to other annual counts. The fourth of July counts focus on quantitatively monitoring the Northeastern population of monarchs as they arrive in the spring and summer. Therefore this data can be used to analyze population trends.
What part can New Jersey residents play?
Monarchs are traveling across New Jersey May through October. There are plenty of simple ways you can help protect this iconic species.

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.

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.
Golden-winged warbler home range
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.
Follow us in February 2016 when biologist Kelly Triece travels to Honduras to see the Golden-winged Warbler in its winter habitat!
