Sciadopitys Verticillata (Japanese Umbrella Pine), #1065-1067, Grace C. Kubat

BIO 140 Arboretum Project

Over the course of the 2021 spring semester, I observed a grove of Japanese Umbrella Pines. These trees are a part of the University's arboretum. In addition to making weekly observations, I researched the cultural significance of the Umbrella Pines. My research will hopefully contribute to future projects regarding the trees and help to enrich the University's arboretum project.

Tilia Cordata (Littleleaf Linden) #1059, Heather Noel Mckee

BIO 140 Arboretum Project

In this paper I studied the Tilia cordata, more commonly known as the Littleleaf Linden, over the course of three months. I included the history and uses of the Linden tree along with its symbolic value in European culture. This tree symbolizes friendship and peace which coincides with the critical concerns of the Sisters of Mercy.

Salve Regina University Tree Inventory And Management Plan 2012, Bartlett Tree Experts

Archives Books

The Bartlett Inventory Solutions Team from Bartlett Tree Experts conducted an inventory of trees on the campus of Salve Regina University in May 2012. The inventory included: identifying trees and attaching to each tree a tag with an assigned tag number; identifying the trees' condition, health, and vigor; recommending risk evaluations and removals of appropriate trees; recommending pruning, soil management, and pest management treatments to promote tree safety; health, appearance, and longevity; and mapping the trees using GPSr hardware and Geographic Information System (GIS) software.

This digital copy of the plan is redacted. Information about the estimated values of individual …

Plant Composition Of Mixed-Grass Prairie Of Cedar Point Biological Research Station, Keith County, Nebraska, David A. Mckenzie

Biology Faculty Publications

This study involved a vegetation analysis of 15 permanent plots established on the short-grass and mixed grass prairie slopes at the Cedar Point Biological Station in Keith County, Nebraska. Ninety-nine species were found in the plots, including members of 75 genera and 31 families. Twenty-one were graminoids, 71 were forbs or succulents, 6 were shrubs and one was a tree. Bouteloua gracilis (19 % cover) and Carex filifolia (15 % cover) were the dominant graminoids at the site, while Yucca glauca (1% cover) and Artemisia frigida (1% cover) were the most frequent forbs. Comparisons of species richness by slope categories …

Interpopulational & Species Comparisons Of The Genus Liquidambar, Diana Duckworth

Masters Theses & Specialist Projects

Growth patterns under controlled conditions and chemotaxonomic techniques involving protein and flavonoid analysis were used to investigate both interpopulational and species comparisons in the genus Liquidambar. Striking differences in budburstinq patterns after a dormant period were seen when comparing L. styraciflua and L. formosana. The latter species showed earlier initiation of growth. Dormancy patterns of L. styraciflua grown under growth chamber conditions showed a latitudinal cline. Cessation of growth occurred later in a Georgia population under both long and short day experimental periods than populations from Missouri and Kentucky. When grown under controlled conditions, flavonoid patterns from L. …

Ecotypic Differentiation In Ohio & Mississippi Populations Of Acer Negundo L., Anthony Greco

Masters Theses & Specialist Projects

Laboratory investigations of Acer negundo populations from two widely separated habitats revealed distinct patterns of ecotypic differentiation in budbursting, leaf fall, and chlorophyll levels. Second year seedlings of Mississippi seed origin had complete leaf emergence before any evidence of budbursting in the Ohio progeny of similar age. Leaf fall patterns showed a clear difference between the two populations with Ohio plants dropping their leaves 2.5 weeks prior to complete defoliation in the Mississippi progeny. Significant differences in chlorophyll levels were demonstrated with the more northern (higher latitude) Ohio population showing consistently greater amounts of chlorophyll per gram dry weight than …

Bulletin 200 - Trees And Shrubs Of The Campus And East Central Illinois, Ernest Stover

Eastern Illinois University Bulletin

The keys to the trees, shrubs and vines have been revised

in an attempt to make them more usable for the beginning student.

The keys to several of the genera, pines, oaks, ashes, willows,

etc., have been rewritten and species added that were not

in the previous printings.

The key to the trees in winter has been added hoping that it

will be helpful to both teachers and students. The identification

of trees without their leaves during the winter is not only interesting

but useful.

The identification of plants is but one phase of their study.

Botany is the basic …

The Relation Of The Native Forest Cover To The Physical And Chemical Nature Of The Soils Of The Mammoth Cave National Park Area, Sheppard Walker

Masters Theses & Specialist Projects

This study was undertaken for the purpose of determining the relation existing between the native forest cover and the chemical and physical properties of the soils of the Mammoth Cave National Park area. The study was suggested by certain references in the literature to a correlation existing between forest cover and the geological, chemical and physical nature of soils of this area. The recent attempt at reforestation in the Mammoth Cave National Park area renders such a study timely, and it is believed that the results reported in this paper will materially aid the Mammoth Cave National Park Commission and …

A Second Report Upon The Native Trees And Shrubs Of Nebraska, Charles E. Bessey, Robert Bolin , Depositor

School of Biological Sciences: Faculty Publications

Dr. Bessey was then Nebraska State Botanist and “Professor of Botany, State University, Lincoln Nebraska.” The State University is now called that University of Nebraska–Lincoln. This document was published as a contribution to the knowledge of the native woody plants of the state. Several reports had been published previously each containing additions and corrections. This report contains a “Special Request” that asked readers around the state to send samples of native trees and shrubs to the author.

The report contains a classification list of the various trees and shrubs along with information about where they can be found. A table …
