Treesearch

Assesses and compares visual preferences for human-made forest openings that differ with respect to the size of the opening, the presence or absence of slash, and the length of time since harvest.

Describes the historical and ecological relations between oaks, fire, and humans and reports the consequent silvicultural options and limitations in managing and sustaining oak-dominated forests.

Abstracts of invited oral presentations and volunteer poster presentations at the First International Symposium on the biology of Adventitious Root Formation, April 18-22, 1993.

Uses a Delphi technique to (1) identify important innovations in recreation resource management, (2) determine their relative importance in meeting recreation management objectives, (3) and gather information about their diffusion and implementation.

Describes RPGrow$, a stand-level, interactive spreadsheet for projecting growth and yield and estimating financial returns of red pine plantations in the Lake States. This spreadsheet is based on published growth models for red pine. Financial analyses are based on discounted cash flow methods.

Describes a computer program designed for data recorders that stores plant lists and computes synecological coordinates from the stored list. The method of synecological coordinates uses plant species present on a site to quantify the site`s environmental factors.

Research results and ongoing research activities in field performance of planted trees, seedling propagation, physiology, genetics, acorn germination, and natural regeneration for oaks are described in 30 abstracts.

Critically examines four electrofishing methods commonly used to estimate the abundance of smallmouth bass in wadeable streams, and provides guidelines for sampling smallmouth bass in streams of Wisconsin and nearby areas.

Describes procedures for evaluating the quality and quantity of habitat for fish in small and medium streams of Wisconsin. Provides detailed guidelines for collecting and analyzing specific quantitative habitat information.

Describes how to use SYCOOR, an interactive Macintosh program written in BASIC for computing and adjusting synecological coordinates. Site synecological coordinates are indices of moisture, nutrients, heat, and light computed from lists of plant species present at the site. Graphs of a species` distribution in moisture-nutrient and heat-light space are also displayed by the program.
