Assisted Natural Reforestation at Modern Harvest, SC



These fields were pasture 10 years ago; since then regeneration has been occurring naturally.  Wind, wildlife and bordering mature trees all deliver seed to the site.  The fields are in late meadow to early forest stages of succession, with:
  • pioneer trees (sweetgum, sumac, pear, persimmon, pine), 
  • vines (greenbriar, honeysuckle, poison ivy, muscodine grape, passionfruit), 
  • forbes (goldenrod, dog fennel, dandelion, wingstem, pokeweed) and grasses,
  • blackberry. 
  • Also, trees of timber/produce value (pecan, cedar, walnut and oak) slowly establishing in sheltered areas.

Our goal is to assist the forest's regeneration.  We can steer it towards specific economic and ecological objectives, like nut/fruit/timber production, wildlife habitat, soil building and carbon sequestration, using the following strategies.

1.  Assisting specific trees.  We can help a sweetgum grow through a blackberry patch, for example, or help a pecan grow through a sweetgum thicket, to accelerate natural succession and favor valuable trees.  Mulching can boost their growth by retaining more moisture and feeding decomposers that enrich soil.  Also clearing a five foot radius around them temporarily "releases" them from soil, water and light competition, to borrow a USFS phrase, as well as add organic matter to the soil.

2. Encouraging natural regeneration.  To reduce our own labor, we can recruit seed dispersers to start forests for us.  We can attract them by installing water features, brush piles, burrows, bird feeders or bird houses; or by ensuring diverse habitat, like a blackberry patch where critters take shelter, or a lone "nuclear" tree where birds perch.  Understanding which trees are spread by which animals, and which habitats those animals require, can help planning this strategy.

3. Focus on strategic areas.  Young, vulnerable trees are more likely to survive and thrive near mature trees, who not only seeded them, but will continue to protect them from extreme weather and enrich the soil around them with leaf litter.  Therefore, starting near an existing forest (like along a stream or property line) and working outwards is the most efficient use of our labor.  Far easier than, for example, planting trees ourselves in an open field, which may require years of maintenance on top of the initial costs of raising and transplanting nursery stock, and which may be more likely to fail.

4. Map and survey project site. should be the first step in planning all of the above strategies.  See how we mapped this site at Reforestation: Mapping


Above, adjacent to the project site are suppliers of seedlings: mature white pine, willow oak, sugar maple and pecan.  Below, before and after pictures of clearing around three sweetgum and a pecan.

Plant Survey
Sweetgum (Liquidambar styraciflua)
Uses - Erosion control, wildlife (seed for birds, squirrels, and 
chipmunks), timber (veneer, plywood, railroad ties, fuel and pulpwood), recreation and beautification
Management - "Young trees are able to withstand crowding, however, they become intolerant to competition with increasing age. Removal of overstory trees results in rapid growth of young sweetgum trees.

Persimmon  (Diospryos virginiana)
Uses - Edible fruits, wildlife (squirrel, deer, coyote, raccoon, birds), timber (golf club heads, veneer), medicine (fever diarrhea and hemmorrhage), ornamental
Management - Tolerates hot, dry and poor soils, pioneer on abandoned pastures, forms thickets from suckers.

  1. Other than just being a habitat for animals, forest produce a good cover for our environment shading us from strong wings and acting as a source of livelihood for our communities everyone should play a part in conservation.
