Between unexpected detours, blocked-off walkways, and constantly clanking heavy machinery, construction sites can cause quite the commotion. Beyond being a personal annoyance and a public eye-sore, local building sites often have adverse effects—like accelerated soil degradation and erosion patterns—on neighboring ecosystems when left unattended. Although topsoil disruption may seem inconsequential, disturbing nutrient-rich soil and vegetation reduces water quality and flow, decimates valuable plant nutrients, and increases the risk of pest-related disease. However, through the use of locally-implemented regulations and soil restoration projects, necessary construction can continue with minimal environmental impacts.
Benefits of a soil standard and revegetation
Provided by the National Cooperative Soil Survey, soil standards provide construction companies—and interested locals—with a complete list of nutrients and potentially harmful chemicals found in tested areas. With an accurate soil composition in hand, contractors and environmentalists alike can monitor surrounding ecosystems, ultimately protecting nutrient-rich topsoil and native vegetation from both natural and man-made disruptions.
Expedited erosion patterns—commonly induced by construction sites—causes soil to compact, creating a barrier impenetrable to water and essential nutrients. However, through revegetation efforts, habitat revitalization is feasible. Revegetating polluted landscapes facilitates organic restoration, invites diverse species of wildlife, and stimulates soil fertility, all of which positively affect on-and-off site environments. Revegetation resources—like Granite Seed—provide contractors and local environmentalists with necessary products and tools, aiding conservation efforts one seed at a time.
Vegetation establishment methods
Construction sites can practice an assortment of revegetation techniques to prevent unregulated erosion, capture harmful sediment, and spread biological nutrients.
Native grasses and wildflowers
Seeding native grasses and wildflowers—also known as forbs—is a vibrant, effective method of establishing vegetation. A diverse range of plantings should be utilized in the revegetation process to ensure maximum protection against droughts, floods, pathogens, and competing plant variations. Take extra preparatory measures when laying different seeds to avoid nutrient-barring incompatibilities.
Utilize nurse crops
Nurse or cover crops are designed to protect budding native seedlings and nutrient-rich soil—via overhead coverage—from harmful elements and erosion. Permanent, regional plants and freshly placed topsoil are more susceptible to sedimentation and erosion. To ensure prosperous native vegetation and soil restoration, utilize the protective services nurse crops have to offer.
Stabilize by sodding
Laying a continuous cover of grass sod can permanently stabilize polluted areas. Sodding obstructs potential erosion, sedimentation damage, and water runoff by preserving the soil surface with lasting vegetation. Sodding is a popular—if not preferred—method of revegetation because of the quick-acting benefits and wide-spread coverage.
Mulching is a lucrative method of establishing revegetation because of its ability to cover rough, uneven terrain. Spreading mulch promotes vegetation development, insulates dehydrated soil, and repairs biological bonds through the use of aerated, nutrient-rich substances. Apply a thin, protective layer of straw, stone, or other synthetic material to surface soil to protect and revitalize organic material negatively affected by construction sites.
Create a buffer zone
In vegetation establishment, a buffer strip refers to any section of undisturbed, native plant growth outlining a land-agitating site, stream, or wetland. Buffer strips live up to their name, creating a necessary barrier between disruption—like construction sites—and established ecosystems. Buffer zones are most effective when presented as dense, well-vegetated undergrowth. A thick, species-diverse buffer protects topsoil from erosion and purifies water sources of contaminated sedimentation.
Protect the environment
Nutrient-rich topsoil provides rural and urban environments alike with natural, biological benefits. Native ecosystems are temperamental—especially when agitated by land-disrupting activities. Vegetation establishment methods aim to protect against projects—like construction—that speed up erosion processes, increase soil degradation, and threaten important organic matter.
