Landscaping


The Bowdoin Grounds division within the Office of Facilities Management maintains 205 acres of campus grounds, consisting of approximately 40 acres of athletic fields, 35 acres of lawns and gardens, and many acres of mixed deciduous and coniferous forests, including the hiking trails in the Bowdoin Pines.

Grounds personnel focus on maintaining healthy plants and a dense turf to prevent weeds or pests. Bowdoin utilizes an Integrated Pest Management program, and has been gradually expanding an exclusively organic treatment of campus grounds over the past ten years.

  • Organic Treatment of Grounds: The Town of Brunswick’s aquifer protection zone includes Bowdoin’s Whittier Field, home of Bowdoin’s football team.  Because of this designation, the college began treating the field organically in 2002. Utilizing an organic program of aeration, compost tea, and hand weeding, over time the college has developed a superb playing field that is completely organic.  Bowdoin has  expanded the organic treatment across 60 percent of the central campus, including the Cleaveland Quad, Main Quad, Coe Quad and the President’s residence and guest house.  The treatments utilize ingredients such as corn gluten, seaweed, bone meal and manure, and pest deterrents such as red pepper and garlic oils.
  • Water Conservation The campus landscapes with native species that do not require irrigation. High visibility grassed areas of campus do receive water during dry weather.  In recent years, as a means of conserving water, the college  installed a below ground irrigation system on athletic fields at Pickard Field  and the Main and Cleaveland Quads.  These systems monitor the moisture in the soil and only water accordingly.  The systems are automated to  operate in the early morning hours before the sun rises to reduce evaporation during the watering cycle.   The campus maintains a mowing height of 2.5 to 3 inches, which encourages deeper root growth, thus reducing the need for watering.  Utilizing mulching mowers, grass clippings are left on the lawn.  On the rare occasion when they need to be removed, the clippings are composted. 
  • Tree Care  Bowdoin maintains a GIS tree inventory of the 1600 trees on campus.  Bowdoin plants a wide diversity of species as a precaution against disease. The College has worked diligently over the past ten years to eliminate parking near tree roots, avoiding root compaction.  Any time a tree dies on campus,  every effort is made to replace it within a year.  For each tree that needs to be removed from the quad, the college plants two trees, gradually increasing the number of trees on campus.  
  • Snow and Ice removal: To reduce the negative impact of salting  during Maine winters, Bowdoin uses a product called Magic SaltTM.   Magic Salt is ordinary rock salt that has been treated with an agricultural by-product of the distilling process blended with magnesium chloride. The result is a product that allows the reduction of salt use by roughly 30%.  Another measure  taken to protect the trees from  winter road and sidewalk salting is the application of  gypsum around the trees, which helps reduce the salt uptake in the roots.
  • Stormwater: Bowdoin is installing its first green roof on its central heating plant in the fall of 2011, after a yearlong trial period. Consisting of various sedums, the roof is expected to absorb water on site, expand the life of the roof and provide a scenic view from the LEED Silver certified Buck Fitness Center. Other low-impact development techniques used to treat stormwater on site include a rainwater capture system on the roof of two dorms (we utilize the water for toilet flushing in the two buildings), and storm water retentions ponds, vegetative swales, infiltration galleries, under drained soil filters, and under drained bioretention cells.  Additionally, surfaces are designed to direct rainwater runoff toward plants and maintain plant health. 
  • Composting  Organic waste from grounds keeping are composted by a local contractor in exchange for loam that is used around campus.  The Grounds Department also chips wood debris to be used on campus trails.
