    Easy to use Excel Spreadsheet Management Tool for Reducing Invasive Animal Density Reprint of summary from:

    McMahon, CR; BW Brook; N Collier, and CJA Bradshaw. 2010. Spatially explicit spreadsheet modeling for optimizing the efficiency of reducing invasive animal density. Methods in Ecology & Evolution 1 53-68.

    I nvasive ungulates with eruptive population dynamics can degrade sensitive habitats, harbor disease-causing pathogens and facilitate the

    spread of weedy plants. Hence there is a need

    globally for cost-effective density reduction and

    damage mitigation strategies. User-

    friendly software tools that facilitate

    effective decision making by

    managers (who are not usually

    scientists) can help in understanding

    uncertainty and maximising benefits

    to native biodiversity within a

    constrained budget.

    We designed an easy-to-use

    spreadsheet model – the Spatio-Temporal Animal

    Reduction (STAR) model – for strategic management

    of large feral ungulates (pigs, swamp buffalo and

    horses) within the World Heritage Kakadu National

    Park in Australia. The main goals of the model are to

    help park managers understand the landscape and

    population dynamics that influence the number and

    distribution of feral ungulates in time and space.

    The model is a practical tool and

    methodological advance that provides a forecast of

    the effects and financial costs of proposed

    management plans. Feral animal management in the

    park is complex because populations cover an

    extensive area comprised of diverse and difficult-to-

    access habitats. There are also large reservoir

    populations in the regions surrounding the park, and

    these can provide immigrants even after within-park

    control operations. To provide the optimal outcomes

    for the reduction of feral animals, STAR is spatially

    explicit in relation to habitat, elevation and regions of

    culling, and applies density-feedback models in a

    lattice framework (multi-layer grid) to determine the

    optimal cost–benefit ratio of

    control choices. A series of

    spatial and nonspatial

    optimization routines yielding the

    best cost–benefit approaches to

    culling are provided.

    The spreadsheet module is

    flexible and adaptable to other

    regions and species, and is made

    available for testing and modifying. Users can

    operate STAR without having prior expert knowledge

    of animal management theory and application. The

    intuitive spreadsheet format could render it effective

    as a teaching or training tool for undergraduate

    students and landscape managers who might not

    have detailed ecological backgrounds.

    Short-term effects of fire on soil and plant nutrients in palmetto flatwoods

    Schafer, JM and MC Mack (2010) Plant Soil 334:433-447

    Fire may have different effects on the relative availability of nitrogen (N) and phosphorus (P) because N volatilization occurs at

    lower temperatures than P volatilization, and fire-mediated changes in soil nutrient availability may affect foliar nutrient

    concentrations. We assessed the short-term effects of fire on soil and plant nutrients and 15N isotopic signatures in a palmetto

    flatwoods ecosystem in central Florida. Fire caused a short-term increase in extractable ammonium (NH4 +) and phosphate

    (PO4 3-). The increase in PO4

    3- was greater than the increase in NH4 +, resulting in a decrease in the soil extractable N:P ratio

    shortly after fire. Similarly, foliar %P of the palmetto Serenoa repens (W. Bartram) Small increased more than foliar %N,

    resulting in a decrease in foliar N:P ratios shortly after fire. Soil δ15N and the difference between foliar and soil δ15N did not vary

    with time since fire; however, foliar δ15N of S. repens decreased after fire. Foliar %N of Quercus geminata Small and ericaceous

    shrubs was positively correlated with soil extractable inorganic N, while foliar %P of S. repens was positively correlated with soil

    extractable PO4 3-. Variation in foliar δ15N after fire and the positive relationship between soil and foliar nutrients suggest that

    both increased soil nutrient availability and reallocation of nutrients from below- to aboveground can be important for plant

    nutrient status after fire in palmetto flatwoods.
