The Forestry Bubble

Posted on by grace.hershberg

The middle-aged bubble does not only pertain to the baby boomer generation. Wisconsin forests are experiencing this age phenomenon as well.  Wisconsin forest data shows a significant bubble of acreage in the middle age class (60-80 years old) with lesser amounts in the very young and very old age classes. This middle age bubble can be attributed in part to the cutover period when many of these forests originated.

Forest Characteristics, Ecology And Management In The Statewide Forest Action Plan

Posted on by grace.hershberg

The success of sustainable forest management starts with a solid plan. The United States Department of Agriculture (USDA) requires each chief state forester to develop a statewide action plan every ten years. The Wisconsin plan, developed in 2020, reflects on lessons learned from the past to prepare for future challenges.

The next 12 posts are related to the “forest characteristics, ecology and management” section of the plan. Goals in this section include providing connectivity between forest patches, as well as increasing the quality and scale of forested habitat for many forest-dependent species.

Seeking feedback on draft chapters of bat HCP

Posted on by Kirsten Held

Cave-dwelling bat populations in Wisconsin are rapidly declining due to a fungal disease known as white-nose syndrome. Some species may soon be listed as endangered under the federal Endangered Species Act (ESA). In preparation for this listing, the Wisconsin Department of Natural Resources is teaming up with the Michigan Department of Natural Resources and the Minnesota Department of Natural Resources to develop a large-scale Habitat Conservation Plan (HCP).

The purpose of this HCP is to obtain a federal incidental take permit under ESA section 10 requesting authorization for the incidental take of bats during forest management activities. The goal of this project is the protection of federally endangered bat species and the continuation of forest management activities in the Lake States.

The Wisconsin DNR will use the HCP to guide forest management activities on DNR-administered land. County, municipal and private landowners may also choose to participate in the plan as a way to continue forest management activities while remaining in compliance with the ESA.

Wisconsin DNR is seeking public comments on a proposed revision to preventative treatment guidelines for Heterobasidion root disease (HRD). Stand-level HRD treatment guidelines were originally released in 2013. A DNR technical team and stakeholder advisory committee proposed a revised version using recent research findings, operational experience, and economic considerations.

The draft document and information about the public comment process can be found at  https://dnr.wi.gov/news/input/Guidance.html#open through Tuesday, October 16, 2018. All comments must be submitted by that date.

The Wisconsin DNR is seeking public comments on a proposed revision to silviculture guidelines for emerald ash borer (EAB). Stand-level EAB silviculture guidelines were originally released in 2007, with periodic reviews and updates. A DNR technical team and stakeholder advisory committee prepared the current version using multiple sources of information, including recent research findings, identification and locations of new EAB infestations, economic considerations, and experience gained from implementing previous versions of the guidelines.

The draft document and information about the public comment process can be found at  https://dnr.wi.gov/news/input/Guidance.html#open through Tuesday, October 9, 2018. All comments must be submitted by that date.

Silviculture Handbook Users: Complete survey by June 22

Posted on by Kirsten Held

By Carmen Hardin, Applied Forestry Bureau Director

We are inviting all users of the WDNR’s Silviculture Handbook  to complete a survey to gather input on how they use the handbook and suggestions for improvement in structure, format and information.

Please complete the survey at https://www.surveymonkey.com/r/VQGTJZQ by June 22, 2018.

This survey request is driven by several factors. The primary need is that the Department of Natural Resources, working with the Silviculture Guidance Team, recognizes the need to take a holistic review of the structure and format of the handbook in an effort to address concerns raised in the Wisconsin Forest Practices Study and by other key users, and to improve overall communication of important silviculture concepts. A goal of this review is to evaluate the organization and presentation to improve the utility and function for handbook users.

This survey request also ties into continued efforts to gain efficiencies to meet the 20,000 hour reduction in investment in forest tax law program administration. The Division of Forestry’s Tax Law Section is looking to move key eligibility and enforcement requirements into the Tax Law Handbook and rely more on the Silviculture Handbook as a resource, similar to the Best Management Practices for Water Quality Field Manual, the Biomass Harvesting Guidelines and guidelines related to forest health issues.

The survey has 23 questions and should take approximately 15 minutes to complete. Please share this survey request with others that you think may be interested in completing it.

If you have questions regarding the survey, please contact Katy Thostenson at 608-535-7049 or kathryn.thostenson@wisconsin.gov.
