Abstract

We measured standing crop biomass and plant phosphorus concentration of Lythrum salicaria (purple loosestrife) and Typha spp. (cattails) in 12 Et central Minnesota wetlands. We wanted to determine if significant changes in plant biomass or phosphorus concentration occur due to displacement of native vegetation by L. salicaria. Significant changes associated with plant conversion imply potential alteration of important wetland functions, including productivity and phosphorus cycling. Our results indicate that Typha has significantly greater standing crop biomass (P < 0.01) and that L. salicaria has significantly greater plant phosphorus concentration (P < 0.001). However, we found no significant difference (P > 0.1) between the two populations in phosphorus concentration per unit area (g P.m-2). Our results are inconclusive regarding potential impacts to whole-wetland phosphorus cycling. However, we have developed the requisite background descriptive database for experimental work on alteration of wetland functions associated with invasion of Lythrum salicaria.
