Effects of frequent fire and mowing on resprouting shrubs of Florida, USA, scrub
Background: Resprouting is an effective strategy for persistence of perennial plants after disturbances such as fire. However, can disturbances be so frequent that they limit resprouting? We examined the effects of fire and mowing frequency on eight species of resprouting shrubs (three oaks (Quercus chapmanii, Q. inopina, Q. geminata), three ericaceous species (Lyonia fruticosa, L. lucida, Vaccinium myrsinites), and two palmettos (Sabal etonia, Serenoa repens)) in Florida scrub using a factorial field experiment. We burned or mowed plots at four disturbance return intervals (DRI) – either annually, biennially, every three years, or once in six years (with all plots being treated in the sixth year to control for time-since-disturbance). We analyzed plant growth responses (height, aboveground biomass, number of stems) based on sampling pre-treatment, and six months, one, two, and four years post-treatment. We also measured non-structural carbohydrates (NSC) and soil properties to evaluate these factors as potential drivers of resprouting responses. Results: Fire temperatures were hot (mean maxima 414-698 C among burn days), typical of larger fires in Florida scrub. Plant biomass and heights were affected by DRI (being suppressed by frequent disturbance, especially initially) and varied among species with palmettos recovering biomass faster and species within the same genus generally showing similar responses. Biomass recovery in mown vs. burned treatments showed comparable effects of DRI and similar trajectories over time. Numbers of stems were affected by DRI, disturbance type, and species. Stems increased after disturbances, especially with less frequent disturbances and mowing, and subsequently declined over time. NSC concentrations varied among species and over time and was positively related to biomass. One-year post-disturbance, soil moisture and organic matter content were higher in mown plots, while pH was higher in burned plots. Given the slightly lower eleva
Tree regeneration after fire: Aspen removal experiment, Aspen stem numbers, biomass and canopy height
This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Includes measurements of aspen stem numbers, biomass and canopy height in clipped and control plots, for samples in 2000 (start of the experiment) and 2002 (experiment harvest on August 16, 2002).
Tree regeneration after fire: Aspen removal experiment, Counts of seedling germination
This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Counts of seedling germination (total seedlings observed) and net establishment (total seedlings surviving to the end of the experiment), by species. These counts are for seeded sub-plots only.
Tree regeneration after fire: Aspen removal experiment, aboveground biomass of seedlings from sown seed
This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Data are total aboveground biomass (g dry weight) of seedlings derived from sown seed (leaves and stems combined). Values are averages of all seedlings in a plot. In control plots, BS and WS were pooled (indicated as SPR).
Tree regeneration after fire: Aspen removal experiment, biomass of 2002 growth of transplanted seedlings
This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Data are biomass (g dry weight) of current year growth (2002, leaves + stems) of transplanted seedlings. Values are averages of up to 3 seedlings per plot (fewer where seedlings died).
Tree regeneration after fire: Aspen removal experiment, soil moisture analysis 2002
This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Data are soil moisture from treatment and control plots measured from a single soil core from each plot sampled on 12 July 2002.
