The Climate Smart Restoration ToolData, Maps & ToolsAppalachian Ridge and Valley Region

Overview

Check out the Beta Version of SeedSmart Now Available!A quick way to determine what to plant and where to source your plant material in a climate smart way. Currently, this beta pilot is only available for the Appalachian Ridge and Valley region. 

Value

SeedSmart was developed as a pilot restoration tool, and is designed for use in the Ridge and Valley of the Appalachians, from central Pennsylvania west to eastern West Virginia, and south through Maryland, Virginia, Tennessee, Georgia, and Alabama. The tool is designed to easily expand to other regions of the United States and Canada.

As a pilot, this tool has not yet been tested. We are seeking feedback from users of this tool in the Ridge and Valley.

Introduction

Setting a goal for restoration is one of the most important, and also one of the most challenging, decisions practitioners face. Our guide recommends the use of ecosystems to inform that decision. NatureServe developed a standardized classification of ecosystems in North America (Comer 2003) that include species composition, range, environmental setting, and other information. This classification was mapped nationwide in partnership with LandFire, GAP, and The Nature Conservancy.

Two versions of the map are updated with new information and maintained by NatureServe (NatureServe 2009). The Existing Vegetation map illustrates natural vegetation (ecosystems), as well as disturbed vegetation and other land uses as it occurs now. The other map, Potential Ecosystem, illustrates natural vegetation presumed to occur in the absence of disturbance. If a site is in poor condition but retains some of its natural vegetation such that the ecosystem can still be identified, the Existing Vegetation map, in combination with a key, can aid the user in identifying the ecosystem(s) at the restoration site. If a site has been completely altered such that no original vegetation remains, the Potential Ecosystem map can be used as a guide.

It is recommended that the user make use of the key to ecosystems at the restoration site. We do this because 1) the map was derived from remote sensing with ground data, but has had limited field verification, and 2) the resolution of the maps (90-m pixel size for Potential Ecosystem, and 30-m pixel size for Existing Vegetation) shows vegetation types as squares, which is, of course, not how vegetation occurs. This is particularly true for ecosystems that occur naturally at smaller scales, or for ecosystems that form a complex of types that are not easily mapped individually.

Features & Benefits

Sourcing seeds and other plant materials

Understanding one’s goal is an important first step in restoration, and using plants characteristic of the ecosystem that naturally occurs at the site will likely increase the chances of successful establishment. The ecosystem description provides information on the dominant vegetation, including geographic variations. Other variations are typical within an ecosystem, such as ephemeral seepage areas within a forest, or openings within the forest where soils are more shallow. The description also provides information on other expected ecosystems in the area. Natural disturbance regimes that maintain ecosystems are also described.

SeedSmart provides guidance in locating areas supporting the same vegetation type(s) as those found at the restoration site. An ecosystem type is characterized by a particular environmental setting that differentiates it from others. Many plant species occupy a number of different ecosystem types, exhibiting tolerance to a range of settings. However, plants become adapted to local conditions (Doherty et al. 2017; Beaulieu et al. 2004; Leites et al. 2012), and those plants collected from a different example of the same ecosystem type are potentially better adapted to those conditions than those that are collected in a different ecosystem. The Existing Vegetation map can be used to locate other examples of the ecosystem types found at the restoration site if local materials are not available.

SeedSmart also analyzes the recent climate conditions of the restoration site (1984 to 2014) to determine whether climate is already changing at the site. If the climate has changed over the past 30 years, the tool then locates other examples of the ecosystem type where the climate of the previous 30 years is most similar to that of the restoration site. Plants in these examples have already survived climate conditions similar to the changing climate at the restoration site, and collection of those materials as opposed to those of more local examples may confer a greater potential for successful establishment and survival in the near term.  

Important information

“Potential ecosystem” is not a prediction of how the ecosystem is predicted to change with changing climate. This map uses the environmental characteristics of the site to interpret what ecological system would be present there NOW if there had not been human disturbance. We are not currently attempting to predict how ecosystems will transform in mid-century. E.g. “Northeastern Interior Dry-Mesic Forest may transition to Central Appalachian Dry Oak-Pine Forest”.  Our approach is to increase the likelihood of successful restoration over the next decade or so by using plants can adapt to the restoration site by growing in the same environmental setting (same ecosystem elsewhere) as the target, and by also finding areas where the past climate is similar to that of the most recently changing climate at the restoration site.

SeedSmart is one approach to restoration. There is a growing body of knowledge and tools, and our recommendation is to make use of complementary tools and data. Two additional tools available in this region are in West Virginia and North Carolina. Both use environmental information at your restoration site to identify previously collected vegetation plot data to inform planting lists. These are particularly useful in areas where an abundance of plot data exists.
