The forested wetland ecosystem team now has recommendations for revisions to your cooperative’s forested wetland indicators. These changes are now open for comment until November 15th. You can either comment at the bottom of this post or email me directly (

Here are the proposed changes to the forested wetland indicators:

Index of forested wetland birds

This index represents a variety of ecosystem features and is already being modeled and monitored for the entire region by the Atlantic Coast Joint Venture.

Proposed change: Remove two species from the Index: Cerulean Warbler (due to it’s extremely small range in the South Atlantic) and Swallow-tailed Kite (due to poor model performance with validation data). The potential habitat models for the remaining species in the index (Red-headed Woodpecker, Chuck-Will’s-Widow, Northern Parula, Black-throated Green Warbler, Prothonotary Warber, and Swainson’s Warbler) define increasingly restrictive constraints on contiguous patch size (up to 350 ha for Swainson’s Warbler) and distance to water (down to 120m for Prothonotary Warbler). Based on validation data, this index with the remaining species also seems to cover many important areas for Cerulean Warblers and Swallow-tailed Kites. An improved Swallow-tailed Kite model is in development and will likely be ready in time for future indicators revisions in 1 – 2 years.

Acres of forested wetland

Overall acreage provides an indicator of whether forested wetlands being inundated by sea level rise are being replaced or restored somewhere else, is well monitored, and resonates with a diversity of audiences

Proposed change: None

Acres of natural habitat near isolated wetlands Index of forested wetland amphibians

Amphibians provide an indicator of the condition and arrangement of embedded isolated wetlands

Proposed change: Direct spatial modeling of isolated wetlands is particularly challenging especially across large areas. This revision proposes to use amphibians and the Priority Amphibian and Reptile Conservation Areas (PARCAs) developed by Southeast Partners in Amphibian and Reptile Conservation as an indicator of the condition and arrangement of embedded isolated wetlands. This same approach is also under discussion in Pine woodland, savanna, and prairie ecosystem indicator revision team.
