The ecological relationship between relative frequency and relative dominance is very important shown in figure 1 and 2. The tree species with the highest relative frequency also had the highest relative dominance and vis versa. The greater the relative frequency/relative dominance the greater the relative dominance/relative frequency of that species. On the ridge top the Burr Oak had the highest importance value and in the forest valley the Elm had the highest importance value. Why did the Burr Oak have the highest importance value on the ridge top? Why did the Elm have the highest importance value in the forest valley? One theory on why Burr Oak had the highest importance value is its resistance to fire. Burr Oak is fire resistance and bigger

Adams and Roger C. Anderson. These researchers wanted to determine which specific species were found along the moisture gradient. By plotting the species importance values along the moisture gradient they were able to determine where species were located. They concluded Blackjack oak and black oak were very common in upland sandy areas and black oak, white oak and shagbark hickory had the highest importance value on the ridge top locations with silt-loam soils. They also determined that red oak, sugar maple, american elm, and burr oak had high importance values on low slopes and stream terraces (Adams 1980). These results were similar to what was discovered in the Ponca State Park study. Based on the Ponca State park study it was determined that Elm’s predominantly grow in the forest valley near a water source and the Burr oaks’s grow on the ridge top which was different between these two studies. This discrepancy could be due to the level of human interaction between the two locations at Ponca as …show more content…
According to SFGate Juniper trees can tolerate both acid and alkaline soils. This tree also can grow in a variety of locations including rocky hillsides or mountainous terrain which is why it was found on the ridge top and not in the forest valley (Juniper 2017). The ridge top was very hilly in places and the forest valley was not. Basswood can withstand short term periods of flooding. Basswood is also commonly used as windbreaker and shade provider (Basswood 2017). This would be why this tree species was found in the forest valley due to the highly level of human interactions and the location of the
