PROTECTING VERNAL HABITATS

Temporary Wetlands

 


WHAT ARE THEY?

Vernal pools or habitats are confined depressions, either natural or man-made, that maintain ponded water for part of the year and are devoid of breeding fish populations. These temporary, isolated wetlands provide habitat to many species of amphibians-several of which breed exclusively in vernal pools-as well as a multitude of insects, reptiles, plants, and other wildlife.

 WHY DO THEY NEED PROTECTION?

Although the NJ Freshwater Wetlands Protection Act has been in place since 1989, it has done little to protect vernal habitats because wetlands <1 acre (most vernal pools in NJ are <0.25 acre) were exempt from the regulatory protection.  Vernal pools could be filled, drained, or modified with a general permit. The loss of this critical habitat put the species that depend on vernal pools for breeding habitat at risk.

 

In 1987, when NJ passed a law to enact much stronger wetland regulations than the federal program, SGP 6

was included as a compromise with building interests. It allows applicants to fill up to one acre of an isolated

wetland – a wetland that has no connection to a surface water body.  This is one of the most commonly

applied-for permits and has resulted in a substantial amount of wetland losses.

 

In 2001, the NJ Department of Environmental Protection adopted regulations to protect vernal habitats by prohibiting issuance of Statewide General Permit #6 which allows filling of isolated wetlands.

 

COURT DECISION  

The New Jersey Supreme Court ruled on July 26, 2004 that the NJDEP exceeded its statutory authority under the NJ Freshwater Wetlands Regulations when it adopted amendments in 2001 that prohibited issuance of Statewide General Permit (SGP) 6 in vernal habitats.

 

The court case ruled that the NJDEP could not limit issuance of SGP-6 in vernal habitats “by way of a rule of general applicability.”

 

Since that time, research has established the importance of vernal habitats as breeding or foraging habitats for a suite of species, including several which are threatened or endangered, for which these seasonally ponded areas play a critical role in their annual life-cycle.

 

ALL IS NOT LOST

The court noted that under N.J.S.A. 13:9B-23(d), the NJDEP still has the authority– on a case-by-case basis – to require an individual permit for any SGP-6 proposal which it determines would result in impacts contrary to the intent of the Freshwater Wetlands Protection Act. And the regulations prohibiting NJDEP from issuing any of the other 25 general permits in vernal habitats remains unchanged. The Act also prohibits issuance of several statewide general permits, including SGP-6, in exceptional resource value wetlands, as established through a Letter of Interpretation (LOI) process, issued by the NJDEP.

 

An LOI process provides the NJDEP with an opportunity to identify specific wetlands conditions on a site. It also allows the municipality to comment on any known vernal habitats within its borders.

 

While some vernal habitats may feature known occurrences of threatened or endangered species and

therefore receive the highest level of protection, many do not have known habitat for threatened or endangered.  As a result:

 

in order to protect known vernal pools, citizens with knowledge of the presence of threatened or endangered species should submit supporting information to the NJDEP.*

And municipalities should make sure that applicants who have development sites that include vernal habitats obtain an LOI from NJDEP to protect these special places to the greatest extent possible.
