As I work to finalize data from this summer’s osprey surveys, I wanted to look back and highlight an important observation: more plastic is being found and recovered from active osprey nests. I guess it’s no surprise when you hear that “18 billion pounds of plastic waste flows into the oceans every year from coastal regions.(more…)

New Jersey’s Status Review of Freshwater Fish

Monday, March 21st, 2016
SEVERAL SPECIES OF FRESHWATER FISH TO RECEIVE IMPERILED STATUS

By Michael Davenport, GIS Program Manager

The New Jersey Division of Fish and Wildlife has recently completed a status review of the freshwater fish species within the state. A total of 53 species were reviewed by a panel of experts and the results of that review were then presented to the Endangered and Nongame Advisory Committee which voted  on March 16th to recommend the status changes. As a result of this status review, ten additional species within the state will be receiving an imperiled status of either Endangered, Threatened, or Special Concern. The date for when those listings will become official is still unknown.

New Jersey’s Species Status Review Process

Wednesday, January 27th, 2016
HOW A SPECIES BECOMES LISTED AS “ENDANGERED” IN NEW JERSEY

By Michael Davenport, GIS Program Manager

How does the state’s Endangered and Nongame Species Program (ENSP) determine whether a species is imperiled or secure within the state? The process for determining a species’ state status is known as the “Delphi” method of species status review and it is a process which Conserve Wildlife Foundation of NJ (CWF) staff assists the state with.

The ENSP endeavors to complete a review of all species currently included on the Endangered and Nongame lists every 5-10 years. In addition, other species groups not currently included on those lists may be reviewed for status as well. At any given time, there may be several status reviews being conducted.

The first step taken in conducting a status review is to identify experts and invite them to participate as a member of a review panel. Members of the panel may be comprised of experts within academia, government agencies, non-profits, or private consultants as well as others.

Once a sufficient number of experts have agreed to participate, staff within the ENSP and CWF will compile background material for the species being reviewed. This may include reports, survey data, and data contained within the state’s Biotics database which is the electronic warehouse for all imperiled species data in New Jersey. This background data, as well as a list of the species being reviewed, and definitions of the status options, are then sent to the panelists for Round 1 of the review.

Delphi reviews are comprised of multiple “Rounds”. For each round, each panelist will choose a status for each species based upon that panelist’s expertise as well as the background material. The panelist then sends their selections and justification regarding each species to ENSP or CWF staff who compile the results submitted by all panelists. The review is completed anonymously, so the panelists do not know the identities of the other participants.

For each species, the panel must reach consensus of at least 85% of the respondents for a species’ status to be determined. If consensus is not reached during the first round, then that species will move on to be reviewed in Round 2. For each new round, the panelists’ status choices during the prior round, as well as all the comments made, are available to the panel, so that reviewers can consider the weight of evidence and other reviewers’ opinions on status as they prepare to vote again. This continues until consensus is reached for all species under review.

Once consensus is reached for all species or, if after four rounds have passed and consensus could not be reached for some species, ENSP or CWF staff will take the compiled Delphi results to the Endangered and Nongame Species Advisory Committee (ENSAC). ENSAC reviews the results and makes the final recommendations on status for those species for which consensus was not reached by the expert panel. Based upon ENSAC’s recommendations, any changes to the Endangered and Nongame lists must go through a formal rule-making process before those changes can be made official.

The Delphi review process is a science-based, anonymous review by those with the most expertise on the species within New Jersey. A great deal of thought and time go into preparing for and carrying out a review and CWF has played a major role in assisting with the process. From the blue whale to fairy shrimp, each species will ultimately receive a state status, leading the way for conservation action.


The following are state conservation status categories; the last, “Not Applicable”, is used only during the status review and is not a legal status category.

  • Endangered
    Applies to species whose prospects for survival within the state are in immediate danger due to one or several factors, such as loss or degradation of habitat, overexploitation, predation, competition, disease or environmental pollution, etc. An Endangered species likely requires immediate action to avoid extinction within New Jersey.
  • Threatened
    Applies to species that may become Endangered if conditions surrounding it begin to or continue to deteriorate. Thus, a Threatened species is one that is already vulnerable as a result of small population size, restricted range, narrow habitat affinities, significant population decline, etc.
  • Special Concern
    Applies to species that warrant special attention because of inherent vulnerability to environmental deterioration or habitat modification that would result in their becoming Threatened. This category would also be applied to species that meet the forgoing criteria and for which there is little understanding of their current population status in the state.
  • Secure/Stable
    Applies to species that appear to be secure in New Jersey and not in danger of falling into any of the preceding three categories in the near future.
  • Undetermined/Unknown
    Applies to a species that cannot be assigned a status of endangered, threatened, special concern or secure/stable because not enough information exists on which to base a judgment.
  • Not Applicable
    Applies to species that do not occur in New Jersey, including occasional non-breeding strays and transient breeders that fail to persist.

New Jersey’s Field Guide to Freshwater Mussels is Here!

CONSERVE WILDLIFE FOUNDATION OF NEW JERSEY RELEASE A NEW STORY MAP: “FRESHWATER MUSSELS OF NEW JERSEY

By Michael Davenport, GIS Program Manager

Freshwater mussels are distant relatives of marine mussels with a life cycle which includes a larval stage where they hitch a ride on fish as a parasite. There are a dozen species native to New Jersey and some species are known to live for over 100 years. This is an often overlooked group of species which deserves greater attention since many species are imperiled and because they are indicator species of water quality.

Conserve Wildlife Foundation of New Jersey (CWF) has partnered with the NJ Endangered and Nongame Species Program to create and release our latest Story Map, “Freshwater Mussels of New Jersey.”

This Story Map is a web-based field guide to New Jersey’s freshwater mussel species. The field guide explores the diversity of this group of species, how to identify them, their life history, threats and conservation measures, as well as providing range maps for each species. This is the only freshwater mussel field guide specific to the state of New Jersey and developed by state biologists.

Photos and interactive range maps are available for all 12 of New Jersey’s native species as well as several non-native species found within the state. Several short videos are also included which demonstrate different methods of surveying for freshwater mussels.

Funding for the creation of this Story Map was provided in part through a New Jersey Division of Fish & Wildlife grant.

Northern Long-Eared Bat Protected Under Endangered Species Act

Remember back in late November when we wrote a blog encouraging our supporters to help the Northern Long-Eared Bat become listed as an Endangered Species? Thanks to those of you who submitted comments to the U.S. Fish and Wildlife Service, it was announced today that the Northern Long-Eared Bat will be listed as threatened and protected under the Endangered Species Act.

 

The U.S. Fish and Wildlife Service has cited declines caused by White-Nose Syndrome as well as continued spread of the disease, as the primary threat to the species. Under the protections of the Endangered Species Act, the Northern Long-Eared Bat now has increased priority for funds, grants, and recovery opportunities.

 

Also announced today, the U.S. Fish and Wildlife Service issued an interim 4(d) rule that will provide maximum protection to the Northern Long-Eared Bat in areas where their populations have drastically declined due to White-Nose Syndrome, but will limit regulatory burden on the public in parts of the country where the bat species is not affected by the disease and the populations are stable. The U.S. Fish and Wildlife Service invites the public to comment on this interim rule until July 1, 2015.

How Can You Help Protect Northern Long-Eared Bats?

  • Do Not Disturb Hibernating Bats
  • Leave Dead and Dying Trees Standing: Where possible and not a safety hazard, leave dead or dying trees on your property. Northern long-eared bats and many other animals use these trees.
  • Install a Bat Box: Dead and dying trees are usually not left standing, so trees suitable for roosting may be in short supply and bat boxes can provide additional roost sites.
  • Get involved with Conserve Wildlife Foundation’s Bat Project!
