woodlands. )all of the vege{ation ~ ~vl~es ~m~ have e~sted at Mississippi Vv~est P. egional Park have developed the sols of ~e park rotc their c,arren[ classifications. Relief Relief is an nup. onant landscape feature m ~vir°nmental management. Differing elevations, slope lengths, slope gradients, and aspec, s can after drainage patterns w-h_ich dic~ where erosion will occur. These dkfferences can also influence vegetation ~7pes, temperature variability, and accessibility. Mom o£:'vhissiasippi West Regional Park has a very. fiat ten-am with 0-3% slopes. The mined graveI pit has slopes that range from 10-20%. The nverbar2< is a seep escarpment with a 60-80% slope. A small section of land by the riverbank that extends from the park boundary at the north western suburb, to the nor~,h western edge of the Husby life es,ate, grades bom a 6-12% slope. Topography has played a large parr in some of the vegetative commumty diSmburaon present at the park. Rebel, along w/th vegetation ~9ape, are the only factors that change across the park. The parent material, climate, and rime have all been consistent throughout M/ssissippi West Reghonal Park. Time The soils of Mississippi Wen have been forming m their current landscape design since the Wisconsin glaciation. The ar~s native veg~maon enr/ched the sands with orgamc rna~er over the course of time. These natural vegelative processes continued up until around 100 years ago when human activities began to influence the soils development through mining and a~mdcuthlml production. These alteraUons have not drastically changed the basic development and property of the soils. The topography was changed · m the gravel pk when ir was mined. Natural femlky and other soil characteristics were changed When much of the land was brou~t into agricultural production around 100 years ago.
