Ecological silviculture in mixed stands: June 2013 workshop review

By Eli Sagor, UMN Extension How do land managers “read the land” well enough to make long term decisions about the future composition and growth of their woods?  One important tool is ecological classification systems. ECS is a framework to identify native plant communities early on, when planning treatments to harvest mature trees and make decisions about what to favor […]

Research review: Tradeoffs between mitigation and adaptation approaches

Forests are complex systems, both because of their many parts and processes and because of the diverse human values governing their use.  Sound forest management approaches recognize this complexity and balance multiple objectives including clean water, wildlife habitat, recreational uses, timber production,  and scenic beauty, based on landowner objectives. In recent years, two new objectives have emerged as priorities:  mitigation […]

Supercharge Your Woods: How to do “partial timber harvests” right

2011 workshop series for Minnesota logging contractors and family woodland owners addressed financial and ecological benefits of “intermediate stand treatments.” Watch a 5-minute video from the 2011 field days: httpv://www.youtube.com/watch?v=TzDl3eq_pu8 (A larger version of the video is here) It’s a simple law of nature: In order to survive, trees have to grow at least a little bit each year.  Unfortunately, […]

Intermediate stand treatments: Logger perspectives (videos)

In recent years, intermediate stand treatments (ISTs) have emerged as one of the most promising strategies to increase the health and productivity of Minnesota’s forests.  ISTs can improve stand growth rates, produce big trees and stand structures typical of old-growth conditions more quickly, reduce forest health threats, and greatly increase economic returns. So what are ISTs?  They include any treatment […]
