Plants were monitored for five consecutive years in six study plots in Oulanka, northern Finland. Sex ratio, spatial distribution of sexes, flowering frequency, number of floral shoots and the number and weight of inflorescences were recorded. In addition, intensity of mycorrhizal fungi in the roots was assessed. Both sexes flowered each year with a similar frequency, but the overall genet sex ratio was strongly female-biased. The bivariate Ripley’s analysis of the sex distribution showed that within most plots sexes were randomly distributed except for one plot. Sexual dimorphism was expressed as larger floral and inflorescence production and heavier inflorescences in males. In addition, the roots of both sexes were colonised to a similar extent by arbuscular mycorrhizal fungi. The female sex-biased flowering ratios reported are not consistent among years and cannot be explained in terms of spatial segregation of the sexes or sex lability.

    FIRE-DEPENDENT FOREST/WOODLAND SYSTEM FDn22 Northern Floristic Region Northern Dry-Bedrock Pine (Oak) Woodland Dry pine or oak woodlands on shallow, excessively drained, loamy soils on bedrock ridges and hillsides or on rock ledges and terraces adjacent to rivers. Crown and surface fires were common historically. Vegetation Structure & Composition Description is based on summary of vegetation data from 47 plots (relevés). Ground-layer cover of forbs and grami- noids typically ranges from 25-75%. The most common vascular plants are Canada mayflower (Maianthemum canadense), wild sarsaparilla (Aralia nudicaulis), large-leaved aster (Aster macrophyllus), poverty grass (Danthonia spicata), wintergreen (Gaultheria procumbens), and bracken (Pteridium aqui- linum). Lichen- and moss-covered bedrock and boulders typically make up at least 25% of the ground layer. Shrub layer is typically dominated by deciduous species, usually with patchy to interrupted cover (25-75%). Lowbush blue- berry (Vaccinium angustifolium), juneberries (Amelanchier spp.), red maple saplings, and bush honeysuckle (Diervilla lonicera) are the most common species in the shrub layer. Subcanopy is usually absent, but when present, red maple and paper birch are frequent components. Canopy is composed of conifers, hardwoods, or conifers mixed with hardwoods, and is usually patchy (25-50% cover), with openings in areas of exposed bedrock or boulders. Red pine and white pine are dominant on many sites. On other sites, jack pine or northern pin oak are dominant. In mixed forests, conifers often form a supercanopy above hardwood species. Paper birch is often present in the hardwood canopy. Landscape Setting & Soils Glacially scoured bedrock—Common. Landscape is hummocky to rugged. Parent material is non-calcareous drift, usually less than 20in (50cm) deep over bedrock.

Mihail Sadoveanu, nr. 3, 700490–Iaşi, Romania Corresponding author: [email protected] This second part of the paper about the vascular flora of Rarău Massif listed approximately half of the whole number of the species registered by the authors in their field trips or already included in literature on the same area. Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E). Key words: Vascular flora, Rarău Massif, Romania, conservation indicators. 1.

    Impacts of seeding and seeding plus mulching treatments on exotic plant invasion and native plant recovery following the 2010 Fourmile Canyon Fire, Colorado Paula J. Fornwalt, PhD Research Ecologist USDA Forest Service, Rocky Mountain Research Station, 240 West Prospect Road, Fort Collins, Colorado 80526 Final Report to Boulder County Parks and Open Space 12 February 2012 Fornwalt PJ. 2012. Impacts of seeding and seeding plus mulching treatments Abstract Following the 2010 Fourmile Canyon Fire, 170 ha (422 ac) of moderately and severely burned areas were seeded with a mixture of quick growing grass species to provide exotic plants with competition during the first few postfire years. Additionally, some seeded areas were also mulched for runoff and erosion control. We established a network of unburned (UNBURN), burned only (BURN), burned and seeded (SEED), and burned, seeded, and mulched (SEEDMULCH) plots to (1) quantify seeded grass germination and establishment, (2) assess the impacts of seed and seed plus mulch treatments on exotic plants, and (3) examine if native plant recovery is impacted by seed and seed plus mulch treatments. We found that the seeding treatments, both alone and in combination with mulching, had no impact on exotic plants during the first postfire year, probably because seeded grass and mulch cover were generally low. The native plant community also appears to be largely unaffected by the treatments at this point in time. Our results provide Boulder County Parks and Open Space with scientific data on the effectiveness of postfire seeding and seeding plus mulching treatments at meeting treatment objectives in the first postfire year.
