Hurricane Effects on a Fagus/Magnolia Forest in Southeast Texas, USA, in the Context of Long Term Forest Monitoring

January 1995 (has links)
In 1986, Hurricane Bonnie passed over Wier Woods, a well-developed mesic forest in the Big Thicket Area of Texas, causing substantial tree mortality and opening several canopy gaps. Mortality was high during the hurricane interval, but did not vary significantly among species. Ingrowth into the 4.5 cm DBH size class was accelerated by the hurricane. Tree growth was largely unaffected by the hurricane; however, small individuals of all species experienced slightly increased growth rates after the hurricane. Mortality in the years after the storm did not decrease or increase. Even though Bonnie caused approximately three times "normal" mortality, there was only a slight decrease in basal area from 1985 to 1987. The low frequency of hurricanes and the modest effects of this hurricane suggest that hurricanes may have limited effects on the structure and dynamics of forests of the Big Thicket.

A Management Study of the Cache Elk Herd

Hancock, Norman V. 01 January 1955 (has links)
The present study was undertaken to acquire additional management information for both the North and South Cache units. It was recognized that effectiveness of elk management could be increased if such information were available as population data, age composition figures, effectiveness of the winter feeding program, herd productivity and mortality, summer and winter distribution, and the inter-specific role of deer and domestic livestock with the elk. The present study was commenced during late fall of 1951. Formal field work continued through the spring of 1953, though limited field work extended through the early 1954 winter. The study has been dedicated to the procurement of elk management information on both the North and South Cache units.
