Bald Cypress Sapling Health Rating Scale

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

If saltwater is applied to a plant, the plant would shrivel up and die. This is a result of the water moving out of the cells in order to try to balance the concentration of solute compared to inside the cell. The water movement out of the cell would cause the cell to shrink and the lack of water would eventually cause the plant to die.

Based on the current conditions of the area, we hypothesis that tree survivability will be highest in elevations above 3,000 feet and below 3,300 feet, highest in slopes between 0 - 45 degrees, and highest in aspects between 0 - 33 degrees. Tree survivability will also be highest in area with the best soil, water quality, and forest health conditions for successful tree sapling growth.

Please record the address of the property where the samples were collected, or—even better—provide GPS coordinates). You will bring these leaves to the college and will identify the trees they came from using accepted scientific methodology. I will give you guidance in how to identify the tree species. (Note that this may involve meeting outside of class time). You will then write a paper, using the same format as your regular lab report, on the identity of the trees, whether they are native to our area or not, and discuss why they might be growing where you found them. Your paper will be reviewed and you will have the option to either accept the grade given, or correcting any problems found. If problems are corrected, your grade will be raised to the maximum and your paper submitted for possible publication online at www.saturnjournal.org. This will be worth 10 bonus points. 3. Extra exam credit. There will be four bonus points available on each of the two lab practicals, and five bonus points on the final lecture exam, for a total of thirteen bonus points. Total bonus points available = 30. When added to your lowest qualifying exam grade, this equates to a maximum of six (6) points added to your final course average. EXAM POLICY: A. Repeating exams. Please note that each exam may be taken once only. Exams may not be repeated because you are not happy

Looking further into the impacts of the Rodeo-Chediski fire the trees saw the greatest impact of the fire. Almost 90% of the trees suffered complete crown kill (Ffolliott, 2008). Either some trees had survived with low severity, were harmed, or dead because of the drought and the fire combined. Even though some of the trees that had faced high severity apparently after having seen what trees had survived the fire yet by 2004 two years after the fire they had died (Ffolliott, 2008). The wildfire also impacted the standardization structure, post-fire mortality of trees, and stocking of tree reproduction on the Steamer Ridge Watershed (Ffolliott, 2008). After the fire had finally been contained the density of the forest had been forever changed.

The graph that has been made explains the relationship between 0the salinity and conductivity including the trials. The graph showed that salinity was increasing and as a result conductivity was also increasing. The trend line showed the direct and stable relationship which was whenever salinity increases conductivity also increases. The equation from excel was y=999.66x+646.4. R2 was = 0.99656. Then we solve the equation to get the answer for the salinity. We start with plugging the conductivity number instead of Y and the we solve the equation to get the salinity which we be 15.85ppt. As a result the salinity of the Seven River estuary is equal to

Saline environments tend to hinder agricultural production by lowering crop yields, often quite substantially. The traditional response to the threat of salinity-induced crop yield reductions is to apply water in excess of plant requirements so as to leach the salts out of the root zone. (Letey and Dinar, 1986).

We performed this experiment with five trees. On each tree we had three treatments: no thorns, normal amount of thorns, and a doubled amount of thorns. The branches were color coded with flagging tape according to the thorn density. Yellow was for super thorny branches, blue stripes indicated the control branches, and blue dots marked the thornless branches. We randomly designated which branches should be super thorny,

Construct back-to-back stem-and-leaf plots and histograms and describe data, using terms including ‘skewed’, ‘symmetric’ and ‘bi-modal’.

Once belt transect lengths and belt widths were established, measurements were recorded. Since this paper focuses on tree seedling and saplings, methods of larger tree measurements and understory canopy cover measurements will not be discussed. Tree seedlings and saplings were recorded only if they fell within the area encompassed by the belt transect length and width. If they did, the four-letter species code was recorded per individual seedling (ex: PIPO for ponderosa pine), its status (1 if living, 0 if dead), height (cm) from ground level, and the number of internodes to determine approximate

The first and most notable symptom of infection on susceptible cypress occurs as irregular patches of crown chlorosis and death, particularly on small and young branches (Granti 1998; Raddi and Panconesi 1981; Wagener 1928, 1939). Closer examination of symptomatic trees reveals the presence of tapering,

Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an oak tree, and needed a total of three different trees per group. Once three different trees were chosen, groups needed three shade leaves and three sun leaves of off each different tree. In total, each group should then end up with 18 leaves for testing. After collecting the leaves, we ran them through the LiCor 3100 leaf area meter to identify the area of each leaf. Major results found by the classes’ mutual data was each one of our p-values were greater than .05. This means that we failed to reject the null hypothesis. Thus, the lab results do not support our hypothesis that Quercus acclimation is greater than Acer SLW, size, and sinuosity.

Plants in natural environments are being exposed to increasing amounts of salinity. One-third of the land being irrigated worldwide is affected by salinity, but salinity also occurs in non-irrigated land (Allen et al., 1994). There are large areas of primary salinity, but secondary salinity can be detected within one hundred years of settlement on an area of land. Drought and salinity are connected because in many regions, raising plants requires irrigation. The irrigation water contains calcium, magnesium, and sodium (Serrano et al., 1999). As the water evaporates and transpires, calcium and magnesium
