Wet Beaver Creek Lab Report

Our experiment was conducted in late January at Wet Beaver Creek. Wet Beaver Creek is located south of flagstaff in the Coconino National Forest. Wet beaver creek has an elevation if 1158 meters, with an average annual precipitation of 16.71 inches, and an average temperature range of 80.8 in July and 43.1 in December. Wet beaver creek features both Perennial and non-Perennial rivers, and is home to many species of trees including sycamore, Juniper, Cottonwood, Alder, Ash, and many more. To test the hypothesis that mistletoe abundance effects tree health and diameter, we quantified the number of trees that did and did not possessed the Big Leaf Mistletoe along a 50m plot from the perennial river edge. We did this by evaluating each tree we saw by eye, looking for signs of mistletoe on the tree. We them recorded the diameter of the trees and a quantified scale of health for the trees between one and three; three being good health and one being low health. We also recorded the number of different growths of Big Leaf Mistletoe on the trees that possessed mistletoe. We did this for the first 50 trees we came into contact with, within our 50 m perimeter from the river. …show more content…

We evaluated the same number of trees as at the perennial however set our 50m perimeter from the middle of the river, rather than at the edge as we did at the perennial site. This is due to the number of trees rooted in the middle of the dried river as well as there being no clear distinction of where the edge of the river would

This week we went to the Conodoguinet Creek. While we were at the creek we did many different things. One of the experiments we did was the Critter Count which was my favorite. Another experiment we did was the Eutrophication Tests. The last Experiment we did was the bobber test.

On the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is.

At noon on April 11th, 2016 my geology 101 lab class conducted a field study of two faults located on East Owens Ave (36.188378, -115.014308). The day was sunny with scattered clouds, but it had rained the day prior. These two faults are of particular importance due to their close proximity to surrounding neighborhoods. Our goal was to see how faults behave in the real world and draw conclusions on the public policy of Las Vegas concerning faults.

The Cullowhee Creek is a small source of water that runs through Western Carolina University. The creek begins further up the mountain, then runs into the Tuckasegee River, which then flows into the Tennessee river, then the Mississippi, and finally, into the Gulf of Mexico. In this activity, we monitored the creek to determine its health. In the Riparian Inventory activity, we rated various aspects of the creek.

Hello! I’m William Westhafer and this is our creek. The Conodoguinet Creek is a 104-mile-long tributary of the Susquehanna River in South Central Pennsylvania. The part we visited is located at Acri Meadows park in Enola. My hypothesis is that if we test for pollution, then we will find small levels.

The temperature saw an overall increase from January to March, with a positive linear slope of 0.0816. The fluctuations in temperature can be attributed to rain events, cold fronts, and other natural events. Discussion The intensity of varied temperature levels directly correlates with the stream’s capacity to perform leaf-litter breakdown. Miller’s Fork experienced a gradual increase in temperature over the course of three months, as the seasons changed from winter to spring, with varying temperature fluctuations caused by natural events (Fig.2). This gradual increase in temperature amplifies microbial activity, enhancing leaf decomposition through oxygen consumption and sulfate reduction (Trevathan-Tackett et al. 2020).

Therefore, if the water temperature is between 12 degrees Celsius and 21 degrees Celsius, it will then sustain plants near and in the river because the ideal temperature for plant growth is 20 degrees Celsius. Methodology: A notebook, phone, thermometer, and pencil were brought to the Assabet

Due to runoff and industrial discharges, the habitat and water quality of the canal have been significantly degraded over time. The canal has four distinct segments, as seen in figure 1. Although they share some characteristics, the segments differ from one another in many ways. As a result, each segment needs to be evaluated and addressed

Introduction: The purpose of this experiment is to determine how healthy Galloway creek is/ is not. The factors we are going to use to determine the health of the stream include nitrate, dissolved oxygen, % saturation, temp, phosphate, pH, macroinvertebrates. Some of the macroinvertebrates that can be found in creeks help determine weather or not a stream is healthy or not. For example if Stonefly Nymph is present in the stream it should be considered healthy. The reason for this is because they are pollution sensitive and are used as bio indicators.

Many readers may argue that the wolves and the rivers have no connect to each other. However, according to the article, when wolves were reintroduced hints of aspen and willow began to regrow. The increase of vegetation caused the land to become less prone of erosion. This helped the water carve the pathway for more water to flow through and shape rivers and other streams of water. Also, readers may add that other animals were the reason vegetation increased.

Runoff in streams and rivers is a massive problem in the Southeastern United States, along with other parts of the world. While each area has different elevations, soil types, and vegetation, it shows that it is a constant problem that all areas show. The definition of runoff can be complicated or simple, depending on the person who explains it. The effects of runoff, seen throughout the different areas, can affect the ecosystem. The ecosystem can be affected by the leading cause of runoff, erosion.

Introduction: Southern New Jersey is home to an area of vast forests which are federally protected by the American Government. This area is known as the Pinelands, and it consists of many different plants, trees, and animals. Here in the Pinelands, all of these different species intertwine with one another, essentially needing one another in order to thrive and survive. Over the years, scientists have begun studying these relationships, today we know this as Ecology.

The blotched tiger salamander (Ambystoma mavortium) of the Southern Okanagan Valley, British Columbia, Canada, was used as a case study for this analysis (Figure 1). Among the driest regions in Canada, the Okanagan is at the northern periphery of the dry, shrub/steppe grassland ecosystem that extends from the Columbia Basin in the United States. Wetlands in the Okanagan are highly dynamic and often inundated only during wet years or seasonally after snowmelt. Further, wetland habitats in the Okanagan are integrated as part of a multifunctional landscape dominated by human land use. Due to limited land for urban development, there is increasing social and economic pressure to develop into wetland habitats.

This has been shown to have happened in the case of rewilding Yellowstone; since the wolves were originally lost from the park, the grazing, of Elk in particular, led to a huge loss in trees and shrubs along the banks of rivers which destabilised banks and reduced rain interception, however since the reintroduction and subsequent drop in Elk population, the number of larger plants along the bank has increased significantly (Beschta & Ripple, 2006), this has led to the banks becoming more stable, and flooding becoming less

Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
