Tb159: Drought And Cold Stress-Induced Morphometric Changes In Tree Rings Of Red Spruce, Richard Jagels, James Hornbeck, Susan Marden

Technical Bulletins

Morphometric analysis of individual, key growth rings might provide a way of establishing “fingerprints” or unique patterns for growth rings produced following different natural or anthropogenic stresses.

Tb158: Milk Processing And Distribution Costs: Maine 1993, Stephan C. Howick, George K. Criner, Stephen L. Jacobs

Technical Bulletins

The objective of this study is to provide an updated estimate of the theoretically lowest achievable costs of processing and distributing milk in Maine. Costs are estimated for a state-of-the-art processing plant assumed to be located in the Portland, Maine, area. The plant produces and distributes a full line of products, including white milk, chocolate milk, and orange juice, and distributes additional products such as cheeses and yogurts.

Tb157: Capture, Care, And Handling Of Fishers (Martes Pennanti), Herbert C. Frost, William B. Krohn

Technical Bulletins

These authors brought fishers into captivity to assess the reproductive cycles of both sexes and to monitor females with known reproductive histories. In addition, kits born in captivity were raised to sexual maturity to monitor growth and development. Here they report on the rates at which fishers were caught, the care and maintenance of fishers while in captivity, and the handling procedures used with 44 fishers taken from the wild and 38 fishers conceived in the wild and born in captivity, during the period from 1990 to 1993.

Tb156: Woody Landscape Plant Cold-Hardiness Ratings, Paul E. Cappiello, Lyle E. Littlefield

Technical Bulletins

The Lyle E. Littlefield Ornamentals Trial Garden has served as an excellent choice for testing winter survival of landscape plants. It is located on approximately 5 hectares of land comprising the highest elevation and windiest site on Marsh Island. The site is in USDA hardiness zone 4a. The soil is highly variable, ranging from a fine sandy loam to marine clay, with many stones throughout. In general, most plants are cultivated in beds mulched with mixed soft wood bark from a local mill. Plants receive supplemental irrigation during the first two seasons after planting, and thereafter irrigation is supplied only …

Beaver Recolonization In South-Central Maine, Laurence Lisle Ii

Electronic Theses and Dissertations

Following a long absence due to over-trapping, beaver (Castor canadensis) recolonized most of their continental range during the middle of the 20th century. The spread of beaver across the landscape was revealed by the emergence of beaver-created wetlands, or flowages. Based on the appearance of flowages on aerial photographs from 1939, 1957, 1974, and 1991, I documented the return of beaver to a 105 km^ watershed in south-central Maine. I sought to determine if certain wetland characteristics—area, perimeter to dam length (p/d) ratio, and watershed size—influenced the order in which sites were occupied by beaver. Also, to gauge the effect …

Tb152: The Effect Of Juvenile Wood On The Properties Of Aspen Flakeboard, Kenneth D. Roos, James E. Shottafer, Robert K. Shepard

Technical Bulletins

While the effects of juvenile wood tissue on solid wood products and paper have been known for some time, little information is available regarding its influence on structural flakeboard. Juvenile and mature wood tissue were identified b y their physical and mechanical properties in quaking aspen (Populus tremuloides Michx.). Sections of juvenile and mature wood were separated from 1-foot bolts of aspen. These sections were used to prepare three distinct types of structural flakeboard : juvenile wood-based, mature wood-based, and one formed from an equal mixture of the two. The panels were tested for selected mechanical and physical properties. The …

Conservation Easements As A Forest Management Strategy, C. Edwin Meadows Jr., Donald J. Mansius

Maine Policy Review

Conservation easements have become an increasingly popular way of protecting private lands that have public value. Maine, like other northeastern states, has a particular interest in conservation strategies given among other things, its natural resource-dependent economy. C. Edwin Meadows, Commissioner of the Maine Department of Conservation (MDOC), and Donald J. Mansius, the Northern Forest Lands Coordinator for MDOC, address the forest management aspects of conservation easements and provide examples of easement land where forest management is permitted. An accompanying sidebar by Chris Spruce describes a conservation easement that has existed for more than a down years along the Penobscot River …
