Measurement Of Throughfall At Two Levels In A Young Aspen Stand, J.R. Clements

Aspen Bibliography

The purpose of this report is to compare measurements of the quantity of throughfall at two different heights above ground level in a seven-year-old sucker stand of largetooth aspen (Populus grandidentata Michx.) This comparison defines the influence rain splash from the forest floor has on the quantity of throughfall catch of trough rain gauges placed on the forest floor.

Net Rainfall In A Multi-Storied Aspen Forest Community, J.R. Clements

Aspen Bibliography

This paper presents mathematical equations describing the relationships between the amount of net rain per storm under each crown canopy and the amount of gross rain per storm in a multi-storied forest community. The relationships were curvilinear and accounted for gradual filling of the storage capacity of the vegetation. The rate of increase of net rainfall was successively less for each crown canopy in turn starting with the uppermost canopy in the forest. The equation coefficients varied in respect of the position of the crown canopies in the vegetal profile and also in respect of variations in vegetal structure within …

Stem Canker Disease Of Red Flowering Gums, W P. Cass Smith

Journal of the Department of Agriculture, Western Australia, Series 4

Of the many native Eucalypts in Western Australia few are more attractive than the red flowering gum.

It flowers generally during the Christmas period and provides a beautiful display for several weeks, with blossoms of several colours including dark red, scarlet, orange and pink.

Behavior Of Pesticides In Plants, Logan A. Norris

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A number of chemicals of diverse characteristics have arbitrarily been classed together on the basis of their use and given the descriptive name "pesticides. " An unfortunate aura of mystery has developed about these chemicals. However, there is nothing unique or mysterious about the chemicals we refer to as "pesticides." Like other chemicals, they have properties which can be accurately measured; they obey all the laws of physics, chemistry, and biology.

Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs

Department of Entomology: Faculty Publications

It is common knowledge to many who have attempted to control bagworms Thyridopteryx sp., that early instars are fairly easy to control, while later larval stages are less susceptible to insecticides. Studies of other insects (Bennett and Thomas 1963, Munson and Gottlieb 1953, Munson et al. 1954, Reier et al. 1953) have shown that as the lipid content increases, the susceptibility to insecticides (especially chlorinated hydrocarbons) decreases. To determine whether the lipid content of the bagworm larva increased with age a series of lipid extractions was conducted.

South Dakota Bird Notes, Keith E. Evans, Roger R. Kerbs

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Approximately 90,000 small stock ponds are scattered throughout South Dakota. The majority of these ponds are less than 10 acres in size, and depend entirely on surface runoff for their water supply. Although their primary purpose is to provide drinking water for livestock, many species of waterfowl and shorebirds use the pond areas for resting and feeding during spring and fall migrations, and for nesting habitat throughout the summer.

Neither the amount of use nor the potential for use by birds on stock ponds in South Dakota is known. Preliminary data presented here are results of waterfowl observations on 13 …

The Hamel Nursery, K S. Cole

Journal of the Department of Agriculture, Western Australia, Series 4

A LITTLE known, but highly productive use of irrigation water occurs at the Forestry Department Nursery, Hamel.

Seedlings of trees and shrubs are raised during the summer for sale the following winter.

Sales are made to the farming community and many trees are used by the Forest Department in its reafforestation programmes.

Some species are checked by heavy grazing although, in the main, this method is far from satisfactory.

Trees Of Western Australia, Charles Austin Gardner

It is not desirable to give locality names to plants unless their range is fully underwood.

Such names can be very misleading.

Review Of Silvicultural Research: White Spruce And Trembling Aspen Cover Types, Mixedwood Forest Section, Boreal Forest Region, Alberta-Saskatchewan-Manitoba, J. M. Jarvis, G. A. Steneker, R. M. Waldron, J. C. Lees

Aspen Bibliography

The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …

Cacodylic Acid As A Silvicide, Maurice W. Day

Aspen Bibliography

This report deals with the effectiveness of cacodylic acid (dimethylarsenic acid) as a silvicide for undesirable trees. Cacodylic acid has been used successfully as an herbicide for the destruction of grasses and weeds. Experimental work with this material was begun during the 1963 field season, and continued during 1964, to permit complete evaluation of the results. It appears that cacodylic acid has considerable potential as a silvicide.

Plant Diseases : Armillaria Root Rot Of Fruit Trees, R F. Doepel

Journal of the Department of Agriculture, Western Australia, Series 4

Armillaria root rot is a fungal disease capable of causing serious damage to both young and established orchards.

Although outbreaks are usually localised, eradication of the fungus and replacement of affected trees can involve the grower in considerable expense. For new plantings, thorough clearing of the land is recommended for preventing losses from this disease.

Trees Of Western Australia. No. 99. The Mottlecah (Eucalyptus Macrocarpa Hook.). No. 100. The Bald Island Marlock (Eucalyptus Lehmannii Preiss Ex Schau.), Charles Austin Gardner

Journal of the Department of Agriculture, Western Australia, Series 4

This species, a shrub between six and 15 feet in height, is the largest-flowered of all the species of Eucalyptus.

The name is intended to indicate this fact, but unfortunately the Greek work makros means "long" and actually the fruit "karpos" is remarkably short in comparison to its diameter, being in fact the broadest fruit within the genus.

Fodder Shrubs In The Murchison, D G. Wilcox

Journal of the Department of Agriculture, Western Australia, Series 4

THE Murchison pastoral country is usually thought of as either having a perennial grass cover, as in the Wandarrie, or as Mulga country with trees and short grass.

It is easy to overlook the small shrubs which occur all over the Murchison in every type of situation, and can provide high quality feed for sheep.

The Messmate Or Stringbark (Eucalyptus Tetrodonta F. Muell). 94. The Sturt Creek Mallee (Eucalyptus Odontocarpa F. Muell), Charles Austin Gardner

Journal of the Department of Agriculture, Western Australia, Series 4

THIS species was originally named by W. V. Fitzgerald from specimens which he obtained from near Pingelly in November, 1903.

The name accedens is from the Latin accedo—to approach or come near—and is here used in reference to the supposed close approach of the tree to the common wandoo (Eucalyptus redunca var. elata).

Mycorrhizae Of Ponderosa Pine In Nebraska Grassland Soils, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

While the genus Pinus has been the subject of extensive mycorrhizal studies there are only a few scattered references to western yellow pine, P. ponderosa, and no detailed descriptive literature on the mycorrhizae of this species. P. ponderosa is indigenous to Nebraska and the one species most extensively grown in local nurseries for windbreaks and farm plantings. Similarly, there is little information on mycorrhizae in the Great Plains between the forested regions of the Mississippi River states and the Rocky Mountains. Because this predominantly grassland area is sparse in natural tree growth the individual tree as an ornamental or …

THE yellow tingle is one of the large forest trees of the lower South-West, and although it possesses many good qualities, its limited range renders it of less importance than its associates—the jarrah and karri.
