Roussel, Megan. The Land Unit- A Fundamental Concept...

The land unit is a crucial landscape in landscape ecology. It provides a foundation for studying landscape ecology relationships. A land unit survey is a method of efficient survey of land characteristics, such as soils, vegetation, and landform expressed in single or overlaying mappings. The more development of a discipline is the aim and the smaller the area, the more direct field observation is necessary. The choice of survey method depends on education, experience, and scientists. A land unit survey is less analytical if there is only one characteristic on the mapping otherwise, it becomes more of inventory. When one begins to overlay the mappings, that’s when the mapping become analysis.

This is one thing that I have struggled with when learning how to properly analyze a site. I am in the habit of collecting data and presenting that data through my own eyes. Though this is the beginning of analysis, it does not properly analyze how certain characteristics of a site share relationships and overlaps or differ completely. This can only be done by combining data mappings at the same and observing their correlation among several layers of information.

It is easy to gather data (as inventory), but as mentioned overlapping the data creates analysis. For me the step further is creation relationships or comparing and contrasting certain pieces allows me to analyze the site even further. What is coexisting with another thing, what is relying on what....etc.

The land unit survey provides brief information on the relationships of sites. It is sometimes hard to decipher which scales to use to relate the varying information. It is also difficult to wade through all of the information to decide which is the most important information to overlay in order to analyze the site.
