Presentation summary:
The presentation will deal with four main issues related to thinning in even-aged hardwood stands at intermediate stages of development, drawing on long-accepted hypotheses and models of stand production and tree growth to articulate a conceptual basis for regulating thinning intensity and judging an appropriate method to use. Broad topics will include:

1. How much to leave
Part 1 will review classic models describing relationships between stand stocking and both gross and net production. It will use well-accepted hypotheses by Langsaeter (1941) and Mar:Möller (1954), as well as more recent findings from Northeastern North America.

2. How stand stocking affects tree growth rates
Part 2 will examine effects of stand stocking level on individual tree growth as hypothesized by Langsaeter (1941), Daniel et al. (1979), and Marquis (1986). It will also consider the importance of enhanced diameter growth in maintaining full net production after a properly controlled thinning.

3. What trees to favor
Part 3 will explore relationships between tree crown position and diameter on post-thinning growth, using hypothesis by Assmann (1970), along with observations by Marquis (1991), Nyland et al (1993), and others.

4. How to make it work
Part 4 will review how these concepts fit with characteristics and expected responses after thinning-from-below and crown thinning in conjunction with leaving B-level relative density. It will also contrast these with effects of dimeter-limit cutting in even-aged stands.

Assessing and Promoting Successful Regeneration in Your Woodland

PA Forests Web Seminar Center

Date: June 13, 2017
Times: noon - 1:00 PM and 7:00 - 8:00 PM, eastern time. Questions often last an extra 15 to 20 minutes

Registration: Presentation URL (for both times): https://meeting.psu.edu/PAForestWeb/

Presentation summary: 

Lack of adequate tree regeneration is one of the top concerns in many woodlands in Pennsylvania and throughout the Northeast. This difficulty in obtaining successful growth of the next generation of trees is caused by three factors: 1) competition from other plants in the understory, 2) intensive browsing by white-tailed deer, and 3) the overstory canopy casting too much shade for seedlings in the understory. Without active management to promote successful regeneration in privately owned woods, the long-term function of our woods is impacted. This webinar will provide an overview of an assessment process woodland owners can use to evaluate regeneration. In addition to the assessment, webinar participants will learn the silvics, including light requirements and growth rates, of some common trees. Lastly, the webinar will provide an overview of stewardship activities commonly used to promote regeneration.

Presentation summary:
This webinar presentation will look at how an understanding of competing plants, deer, and light can lead to successful forest regeneration and the sustainability of hardwood forests. The regeneration, or re-growth, of forests requires that sufficient numbers of desirable trees seedlings become established following a timber harvest. Often times, regeneration is not easy. Regeneration failures and re-growth of less desirable tree species is commo 
n. Competing plants, over-browsing by deer, and insufficient light to the forest floor interfere with tree seedling establishment and growth. Forest sustainability is threatened without adequate forest regeneration. This presentation provides information on key practices used to successfully establish hardwood forest regeneration.

Gypsy Moth: A Persistant Invasive Forest Pest In North America

Presentation summary:
This webinar will explore the history of gypsy moth, and when and how to use different strategies to limit spread or control the impacts of an outbreak. The gypsy moth was accidentally introduced in Massachusetts in 1869 and has slowly expanded its range through eastern North America. In regions where the species has become established, outbreaks are a recurrent phenomenon; populations exhibit some regularity with 5-10 years between population peaks. While most defoliation events have minimal long-term impacts on forests, some stands may experience extensive mortality and at a regional level it is possible to observe a significant decrease in the volume of host oak species associated with outbreaks. Considerable success has been achieved at reducing the rate of spread of the gypsy moth into new regions of N. America. Within the infested area, prevention of outbreaks is challenging but suppression of outbreaks may be justified in high value forests.
