Measures Of Plant Physification And Environmental Analysis

Every forest has a story to tell. By looking closely at its habitants, that story can be interpreted. Much of this narrative is written in the trees: their age, their tolerance to shade, and the rate at which they grow are all characteristics that can imply a lot about their environment. Exploring these relationships and how they connect with each other can indicate the health and history of the land. Heiberg Forest, located in northern New York, was once used for agricultural purposes in the 1800-1900’s. (Nowak, Lecture Notes) Much of the land once used for farming was left to regrow back into a young forest. The life history of different tree species can be determined by examining the most common species in Heiberg.

The purpose of this experiment is to observe secondary succession at Umass Dartmouth and test the prediction that diversity increases through ecological succession. Students went outside to the lawn underneath the wind mill on campus. 3 transect sites were located by the instructor. Students predicted the species and percent cover of each species on each trail site. Bar charts were made to compare the number of species in each transect. Pi-charts were made to compare the percent coverage of species in each transect.

By comparing the topography, soil moisture levels, relative humidity, and wind speed of the upland Savanna and Bottomland forest we will be able to compare and contrast between these two vegetation zones. The data collected in the investigation will be used to test the hypothesis that the bottomland forest has a higher degree of shrub layer cover than the savanna. The higher level of shrubs in the bottomland forest might be attributed to the space available for shrub layer species. In addition, the data collected will confirm that the bottomland forest has a higher tree density than the

Fire has long been understood to have an impact on the ecosystem of our native woodlands, but it is only recently that we have come to understand its importance in maintaining the ecosystem. This report takes samples of the flora structure and growth in two different areas of Anstey Hill Recreation Park. The first was last burnt in 1995, and the second burnt in 2012. The results of these samples can be compared to data sampled in 2011, when the 2012 burnt area had not been burnt since Ash Wednesday in 1983.

Lab one introduces the basic concepts and processes of remote sensing and gives a better understanding of multiband images, color compositing, and contrast enhancement. The following were the objectives for the lab to help introduce these concepts and processes:

larger vegetation zones to the way we should understand the ecology of the land scape.

The reduction of vegetative cover during and after fire can have a severe negative impact on several different factors including: water quality, soil erosion, wildlife and threatened or endangered species, introduction or spread of invasive and exotic species, and economic or social impacts to the surrounding communities. We will implement a vegetation monitoring protocol that will help guide us in restoration and recovery efforts of the High Park fire scar and the surrounding areas and watershed. A collaboration with the US Forest Service will be aggressively pursued in the hopes that a combined use of the Forest Inventory and Analysis (FIA) program and our separate vegetation monitoring protocol can be utilized. We will use the burn severity field data collection points and cross-reference them with the FIA data points to see if there is any overlap between them. If there is then the FIA data points will be given preference as those points can possibly provide more information than solely High Park Fire data collection points. If there is not the ability to utilize the FIA data collection points, due to privacy, cost, or unforeseen reasons, then the High Park Fire data collection points will be

Images were analyzed in GIS to identify and map features such as woody debris, rock outcroppings, shifting versus stable sand, and smooth limestone bottom.

To see the differences of the two sites, basal area, density, species richness, and the Shannon diversity index were used. Basal area and density is the average amount of space of trees in hectares. Basal area is taken using the tree diameters while density uses the number of trees. Species richness is the number of species found. Abundance of each species is used to find the Shannon diversity index. The Sorensen similarity index compares the areas based on the number of the same species. Also, different species were looked at to find the relative basal area, relative density, and importance value of the trees. There were differences and similarities in both

We live in an age where most environments on earth have been impacted by anthropogenic activities. Chapin III et al (2001) contend that, “humans have been a natural component of most ecosystems for thousands of years” (p. 14). Humans interact with the environment in many ways: landscape modification, agricultural activities, urbanization, urban sprawl, carbon dioxide (CO2) emissions, stormwater runoff, and so forth; these anthropogenic activities can have detrimental environmental results. Satellite imagery, aerial photographs, and digital data can be used to analyze how anthropogenic activities impact environments spatially and temporally. This study will investigate how land cover has changed in the D’Olive Creek Watershed, located in Baldwin County, Alabama via the use of geographic information systems (GIS) and remote sensing methods and technology. For the purpose of this study, “land cover” refers to how much of a region is covered by specified land and water types (e.g. forests, wetlands, impervious surfaces, and so forth).

Used navigation device to find the longitudes and latitudes to the location of the sweetgum and black oak tree. Took pictures twice a week of the trees changes over the weeks and Observation the process of leaves changes and leaves falling from the weather conditions. The data we gather will be Compare from previous data from Project

With new technology such as satellites systems, low altitude photography and side looking radar scientists now figure that the world is losing about twenty million hectares of tropical forests annually. It has been suggested that the high deforestation rates are caused partially by the fact that the new surveys are more accurate and thus reveal old deforestation rates that were miscalculated with previous methods (Westoby, 202).

Figure 1: These line graphs illustrate the 12 samples that derived from the 6 data pairs for each pasture. To restate, these samples were collected from two pasture sites in the BLM’s Twin Lakes grazing allotment of Davenport, Washington. The first graph (a) represents the wet weight (kg/ha) in the function of the ocular estimate (kg/ha); whereas, the second graph (b) represents the dry weight (kg/ha) with the function of the estimated wet weight (kg/ha). A trendline, best fit linear equation, and R2 values were added. Upward slopes are observed.

The reserve is surrounded by highly modified landscapes dominated by intensive agricultural and horticultural land use. Common land use for surrounding areas include the growing of cereal crops, grapes and citrus (DOC Gray's Bush. n.d).
