![]() ![]() (2005) Effects of understory prescribed burning on shortleaf pine ( Pinus echinata Mill.)/mixed-hardwood forests. Cover of fireweed, cranberry and Populus spp., as well as the root sucker density of Populus spp. Cover of herbaceous plants was visually estimated in late July 1999. Four burned (in May 1999) and four unburned 2 x 2 m plots were established within each of six 10 ha forest units. root-suckers (burned: 25,400 unburned: 35,500/ha) were similar between treatments. (burned: 4% unburned: 6%), as well as the density of populus spp. The cover of fireweed was higher in burned plots (burned: 18% unburned: 4%), while the cover of cranberry (burned: 2% unburned: 2%), herbs (burned: 6% unburned: 7%) and populus spp. ![]() 2003) found that prescribed burning increased the cover of fireweed Epilobium angustifolium but not the cover of cranberry Viburnum edule, herbs or populus spp. Natural Areas Journal, 22, 43-52.Ī replicated, controlled study in 1999-2000 in boreal forest in Alberta, Canada (Frey et al. (2002) Response of understory vegetation and tree regeneration to a single prescribed fire in oak-pine forests. All lines were located in an 11,000 ha study area. Data was collected in 2000 using five lines of 30 quadrats (1 × 1 m) placed in burned sites (prescribed burn in 1996) and ten lines of 30 similar size quadrats placed in control sites (unburned since 1986). Native plant abundance at the small scale (burned: 38-39 unburned: 29/m 2) and large scale (burned: 1,138-1,172 unburned: 876/30 m 2) was higher in burned than unburned plots. The number of native plant species at the small scale was higher in burnt than in unburned plots (burned: 12-13 unburned: 10/m 2), while the number of species at the larger scale was similar between treatments (burned: 57 unburned: 51/30 m 2). Forest Ecology and Management, 148, 63-77.Ī site comparison study in 2000 in a Mediterranean jarrah Eucalyptus marginata forest in Western Australia (Burrows, Ward & Cranfield 2002) found that prescribed burning increased the abundance of native plants at large and small scales and their species richness only at small scale. (2001) Longleaf pine and oak responses to hardwood reduction techniques in fire-suppressed sandhills in northwest Florida. Referenced paper Provencher L., Herring B.J., Gordon D.R., Rodgers H.L., Tanner G.W., Hardesty J.L., Brennan L.A. ![]() Data were collected in 1995-1996 in 5-10 burned (prescribed fire in 1994-1995) and five unburned plots (20 × 20 m) in each of three bauxite mine sites rehabilitated in 1981, 19, and in ten similar size plots in native forest sites (control). The number of native plant species was higher in burned (40/80 m 2) than unburned plots (28/80 m 2) and the highest in native forest (64/80 m 2), while plant diversity was lower in unburned and burned plots (Shannon–Weiner index: 2.3 in both) than native forest (3.2). Weed density was higher in burned (6/m 2) than unburned plots (3/m 2) and native forest (2/m 2). The density of all plants was higher in burned (35/m 2) and native forest (32/m 2) than unburned plots (6/m 2), while their cover was lower in burned (10%) than unburned plots (48%) and native forest (60%). Forest Ecology and Management, 114, 199-213.Ī replicated, controlled study in 1994-1996 in Mediterranean jarrah Eucalyptus marginata forest in Western Australia (GRANT & Loneragan 1999) found that prescribed fire in restored forest sites increased plant species richness and density, but decreased plant cover.
