Conservation value of forests attacked by bark beetles: Highest number of indicator species is found in early successional stages
-
Heavy natural disturbance in large protected areas of former commercial forests increasingly evokes European parliaments to call for management intervention because a loss of habitats and species is feared. In contrast, natural early successional habitats have recently been recognised as important for conservation. Current knowledge in this field mostly results from studies dealing only with selected taxa. Here we analyse the success of species across 24 lineages of three kingdoms in the Bavarian Forest National Park (Germany) after 15 years of a European spruce bark beetle (Ips typographus L.) outbreak that led to rapid canopy opening. Using indicator species analysis, we found 257 species with a significant preference for open forests and 149 species with a preference for closed forests, but only 82 species with a preference for the stand conditions transitional between open and closed forests. The large number of species with a preference for open forests across lineages supports the role of this bark beetle as a keystone species for a broad array of species. The slowdown of the outbreak after 15 years in the core zone of the national park resulted in less than half of the area being affected, due to variability in stand ages and tree species mixtures. Our case study is representative of the tree species composition and size of many large protected montane areas in Central European countries and illustrates that (1) natural disturbances increase biodiversity in formerly managed forests and (2) a montane protected area spanning 10,000 ha of low range mountains is likely sufficient to allow natural disturbances without a biased loss of closed-forest species.

Beaver (Castor canadensis) mitigate the effects of climate on the area of open water in boreal wetlands in western Canada
-
Shallow open water wetlands provide critical habitat for numerous species, yet they have become increasingly vulnerable to drought and warming temperatures and are often reduced in size and depth or disappear during drought. We examined how temperature, precipitation and beaver (Castor canadensis) activity influenced the area of open water in wetlands over a 54- year period in the mixed-wood boreal region of east-central Alberta, Canada. This entire glacial landscape with intermittently connected drainage patterns and shallow wetland lakes with few streams lost all beaver in the 19th century, with beaver returning to the study area in 1954. We assessed the area of open water in wetlands using 12 aerial photo mosaics from 1948 to 2002, which covered wet and dry periods, when beaver were absent on the landscape to a time when they had become well established. The number of active beaver lodges explained over 80% of the variability in the area of open water during that period. Temperature, precipitation and climatic variables were much less important than beaver in maintaining open water areas. In addition, during wet and dry years, the presence of beaver was associated with a 9-fold increase in open water area when compared to a period when beaver were absent from those same sites. Thus, beaver have a dramatic influence on the creation and maintenance of wetlands even during extreme drought. Given the important role of bea- ver in wetland preservation and in light of a drying climate in this region, their removal should be considered a wetland disturbance that should be avoided.

Carbon Dynamics of the Forest Sector
-
Main points: The basic ecosystem science behind carbon dynamics in forests is relatively straightforward (really!).This science doesn’t seem to be applied very routinely in the policy arena. This mismatch is undermining the potential of the forest sector in helping to mitigate greenhouse gases in the atmosphere

Buried by bad decisions
-
From the text: Alas, research shows that when human beings make decisions, they tend to focus on what they are getting and forget about what we are forgoing.

Products and Tools for Energy Modelling
-
Models of wind, shale gas, and coal development for the entire study area have been created to predict potential future energy development and impacts to natural resources within the Appalachians. Models and data from all development projections populate a web-based mapping tool to help inform regional landscape planning decisions.

Assessing Future Energy Development
-
Assessing Future Energy Development across the Appalachian LCC uses models that combine data on energy development trends and identifies where these may intersect with important natural resource and ecosystem services to give a more comprehensive picture of what potential energy development could look like in the Appalachians. A web-based mapping tool allows policy makers, land management agencies, industries, and others to see where development may likely occur and intersect with important natural values to inform regional landscape planning decisions. Ultimately this information is intended to support dialogue and conservation on how to effectively avoid, minimize, and offset impacts from energy development to important natural areas and the valuable services they provide.

Conservation Strategy for Imperiled Aquatic Species in the UTRB
-
The Strategy provides guidance to Field Offices in reevaluating current ("status quo") conservation approaches in order to deliver the most cost effective approach toward the conservation and management of imperiled freshwater fish and mussel species in the Upper Tennessee River Basin.

Data Needs Assessment Research Update
-
This presentation from Dr. Robert Baldwin of Clemson University provides an update to the Steering Committee on the Appalachian LCC funded research project. The Data Needs Assessment project is evaluating existing spatial data, assembling public data in geodatabase, defining conservation planning tasks that can be accomplished, identifying problems to address if data gaps are filled, interpreting uses of data, and conducting analysis of ongoing planning efforts.
