Impact of wildfire and seeding on the range plant community in the dry forests of southern British Columbia
Introduction Much controversy exists over the use of seeding as a rehabilitation tool after wildfires.The role of using seeding to limit invasive weed spread is poorly understood and some findings suggest that the seed mixes themselves could be considered invasive and lead to a decrease in species richness of the native plant community ( Keeley 2006 ).Also,it has been well documented that,although much postfire seeding occurs,not much quantitative monitoring occurs to assess whether or not the seeding was effective ( Robichaud et al.2000 ).The objective of this study was to track vegetation change in seeded versus unseeded areas that had been impacted by wildfires and specifically to determine if seeding after wildfire 1 ) is an effective method to reduce weed invasion and 2) impacts the native plant community that may become established on the site.
