Several animals, including squirrels and porcupines, can chew or strip bark from trees. This can occur on hardwoods and conifers, older trees and young saplings. Damage can be enough to kill branches or even the entire tree.

Although it has warmed up, the cold weather is still fresh in everyone’s minds, leaving insect and forest lovers alike wondering how insects survive temperatures that cold.

The Wisconsin Department of Natural Resources Forest Health staff has received several questions over the past month about how insects survive cold weather in winter and whether the January temperatures were cold enough to kill insect pests.

The Forest Regeneration Monitoring (FRM) program was initiated to better assess the status of naturally regenerating forests across the state and to provide data on forest regeneration success or failure in relation to deer herd population density across Wisconsin. Previous forest monitoring methods were not intensive enough to tell a precise, county-level story of the impacts of deer browse (herbivory) on forest regeneration or the quality of the forest habitat available to deer.

EUDR Update: Changes In 2025 And The Hardwood Industry’s Path To Compliance

American Hardwood Assured (AHA) is a free, AI-based digital platform developed by the American Hardwood Export Council to verify that U.S. hardwood products are legally harvested and deforestation-free.

Understanding The EUDR And Impacts On The U.S. Forest Products Sector

For those who haven’t been keeping up with international policy, the European Union Deforestation Regulation (EUDR) is an environmental policy proposed to ensure that products sold within the EU do not contribute to global deforestation or forest degradation. The regulation targets seven key commodities—cattle, cocoa, coffee, palm oil, rubber, soy, and wood—that are major drivers of deforestation for agricultural expansion. While the goals of the EUDR are widely supported by environmental and industry groups, its original compliance requirements created significant, and potentially insurmountable, challenges for the U.S. hardwood industry. This article explains the critical updates and delays announced in late 2025, details the proactive solutions being developed by industry groups like the American Hardwood Export Council (AHEC) and American Hardwood Assured (AHA), and outlines a clear path forward for forest products companies. These recent developments have shifted the compliance conversation from crisis to a more manageable, strategic response.
