On September 17th, 2015 our group went on the Orange Trail of the State Botanical Garden of Georgia in Athens, Georgia to collect data for our lab. The biome of this area that we explored fit a temperate deciduous forest type. We walked along the trail and picked random spots to start measuring our transects. We measured DBH size and canopy coverage at 10, 20, 30, and 40 meters respectively along each transect for a total of six transects. We used a densitometer to measure the percent of canopy coverage of the tree closest to the center of the sampling points along each of the transects. We used a measuring tape to measure out 10, 20, 30, and 40 meters respectively along each of the six

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.

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.

The Texas snowbell, also known as Styrax texana is a flower located in the Edwards Plateau of Texas. They are found in Asia, North and South America, and the Mediterranean (Fish and Wildlife Service). Three recognized species exist in the Edwards Plateau: texana, platanifolius, and stellatus (Fish and Wildlife Service). S. platanifolius is found in the east and north of Texas, whereas S. stellatus is found in the south. S. texana however, grows in the west. Through examination of its morphology, it can be determined that the three species are closely related to one another. Their forms and structures are similar, but they evolved and live under different conditions and habitat.

The ancient forests of the Northeast aren’t the only aspect of the bioregion that’s fate have been at perpetual risk since the early settlement of Europeans. There is no question that forests still dominate the landscape of Northeastern region accounting for “60% of the total land area, and in New England alone, the coverage is 80%”. Still the species that exist within the understory of the forests have undergone an equally dramatic transformation because of human interaction with the land and the harvest of its resources. Some species in the understory of the mixed forests of the Northeast have been driven out of the region, are under intense ecological pressure, are on the brink of extinction, or have already gone extinct in the region. Perhaps one of the most harmful and impactful effects colonization of the Northeast has had on the resources of the land is the introduction of non-native species and diseases into the region. Over time the overall makeup of the forests have changed drastically as an example, “…the American chestnut once made up as much as 25% of the trees in some areas and was economically the most important hardwood in the Eastern forests”. The introduction of chestnut blight at the turn of the century accounts for

In the fall, there can be high species richness, but also there is the potential for the populations to still be affected from the hardships of summer months. The identification of species is more difficult because reproduction season typically takes place in the cooler months and therefore does not accurately represent the environment’s quality and species richness (Ontario Ministry of Environment, 2017).

Nectar and pollen attract a diverse collection of nectar fedding mammals and birds, these animals feed on inscets that are drawn by the great quantity of flowers located there. Heathlands are highly fire prone and the fire regime (frequency, intensity, and season of occurrence) has an enormous effect on composition and structure of habitat. Animals too are affected by this regime. Increasing time since fire may create a variety of habitats within the heath that suit different species, while mass post-fire flowering provides an abundance of food (Evvironment.NSW.gov.au). most of the plants in the heathlands produce large seeds that contain nutrients to make sure they establish even under the harsh conditions, this prevents spreading by wind or the feathers and fur of animals. This is overcome by specialised lipid- rich foods that are on the seeds, these lipid rich foods are food for ants, ants then collect the seeds and store them in their nests, they later then detach the foods from the seeds and discard the seed. This spreading and burial of the seeds protects them from intese bush fires and predators that eat seeds, this is still increasing moisture to soil. If the tweed council were to develop further it would decrease the flora that many animals and humans themselves rely

“Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped” (“Dormancy”). Some native plants have learned to adapt to grow a mixture of both short and long roots, so they can absorb moisture from both depths. After the winter season, the deeper roots reach down to absorb the water that has soaked into the deeper ground. Once the water lower in the ground has been absorbed into the tree, the plant uses its shallow roots to begin absorbing the moisture at the surface (Schwinning, Susan. “Sensitivity”). Exotic plants in a new area can cause irregular forest fires, floods, and other unwanted natural disturbances. To prevent these disturbances from occurring, Exotic Plant Management teams are trying to remove unnecessary plants that are only hurting the soil. The Exotic Plants team gives the people taking care of the plants two recommendations. First, they recommended to not worry as much about the bigger exotic plants and try to eliminate the weeds and exotic grasses. Second, is to put as much effort into restoring the native plants that are struggling through the droughts (Daw). Cold season shrubs are one of the few native plants that were not affected by the change in the climate

The Acadian forest in Canada takes up 12.1 million hectares, and can be distinguished from other parts of Canadian forests by its location in the lowlands and deep valleys and by its mixed hardwood and softwood composition. The position of these trees in deep valleys isolates them from other forests, and limits their ability to further naturally spread their population geographically, and causes them to be more significantly impacted by disturbances. The Acadian forest region covers the Canadian provinces of Prince Edward Island, Nova Scotia, and New Brunswick, with a rich diversity of plant and animal species consisting of many shade-tolerant trees and lichens. Yet these shade-tolerant trees are slowly transitioning into small seedlings as logging practices abolish old trees. The old-growth hardwood population in specific provides critical habitats for animal species though these trees are declining in numbers due to extensive logging. With the declining old-growth trees, the number of critical habitats will also decline and animal species will most likely die out. These regions are affected by climate change at the same time, which increases the vulnerability of Acadian biodiversity.

Some tree species were only prevalent at the perennial site compared to the non-perennial site. Higher abundance on cottonwoods could reflect their deeper rooting systems and thus more reliable water resources. A study conducted on Pacific Northwest Trees showed that the larger trees were reliant on greater amounts of stored water for higher levels of photosynthesis, furthermore there were different percentages of water use per tree species (Phillips, 2003). This supports our findings as some tree species were host to more mistletoe than others. This may due to the different amount of water the trees absorb and use. Larger trees such as Populus fremontii. Tree specific factors may affect susceptibility as well. Sycamores are proposed to have defenses that form physical/chemical barriers prevent colonization parasites, this may explain why we saw little to no mistletoe on Planatus wrightii’s at either site (Grime and Pearce 1995). Furthermore alders have an important symbiotic relationship with Frankia alni, a nitrogen fixing bacteria that receives sugar from the tree in return for the nitrogen it supplies (Porter 2013). This explains why we saw the most even mistletoe distribution over our two sites on Alnus

Whitetail deer have come to be known as a keystone species, species known for affecting other organisms in an ecosystem. Deer are known as a keystone species in forest habitats such as in the Eastern United States because they are capable of destroying potential forest habitat of other organisms (McShea and Rappole, 1992). For example, deer have a negative impact on forest ecosystems by trampling and over browsing over vegetation, without creating any habitat for other native species. Throughout the eastern United States, the abundance of white-tailed deer (Odocoileus virginianus) has increased dramatically over the last century (Taggart and Long, 2015). Population increases could be due to increased habitat fragmentation from land development, reduced predators and/or hunting pressure. Individual deer ranges varied during seasonal times, deer movements are usually greatest during the peak breeding months from late fall through winter (Williams et. al, 2012). Regardless of the cause, high deer densities can have significant effects on plant communities such as plant decay and/or even death. Deer consume a large amounts of plant biomass (leaves, buds, flowers and fruits) and directly reduce the growth, reproduction, and survival of herbaceous and woody plant species (Shen et. al, 2016). The impacts of white-tailed deer on forests along the Eastern United

The experiment was conducted in Sheboygan County at three locations of varying distance from Lake Michigan, where they were surveyed for the occurrence of the invasive tree species black locust. The first location, Kettle Moraine State Park, is located 20 miles inland west of Lake Michigan. As its name suggests, this location has a combination of kettles and moraines. Kettles are steep side impressions in a landscape while moraines are linear deposits that accumulated at the edge of an ice sheet. This creates a rolling hill landscape that can create quite the diversity of vegetation. This site was dominated by mostly sugar maple with the occasional red oak and birch. There was very little ground coverage, due to the dense shade cast by the

In Area 2, the species with the highest dominance value was the Oregon White Oak (70.6%). Oregon White Oaks provide shelter, housing, and food to various animals as well. Diversity of birds is often higher in Oregon White Oaks than in an adjacent coniferous forest. Using the dominance data, it tells us that at this moment in time Oregon Oak and
