Slender Tree-Fern Report: Threatened Species Detection & Rainforest Investigation Within Vicforest Logging Coupes: 827-513-0017 & 827-515-0006. FFGA Threatened Flora Species: Cyathea cunninghamii (Slender Tree-fern). Rare Ecological Vegetation Class: East Gippsland Foothills Warm Temperate Rainforest EVC 32. Rainforest Site Of Significance “Mt Buck-EG42” Mt Buck, Curlip Forest Block, East Gippsland. Abstract: Sections within and adjacent to Vicforests clear-fell logging coupes 827-513-0017 & 827-515-0006 were investigated to identify the presence of rainforest & rare or threatened flora species and other biodiversity conservation values. Rare or threatened flora species presence was documented and species location details and photographic records were obtained. This investigation identified the presence of Cyathea cunninghamii (Slender Tree‐ fern) adjacent to Vicforest clear-fell logging coupes 827-513-0017 & 827-515-0006. Analysis of this information and spacial data of other known records of Cyathea cunninghamii (Slender Tree‐ fern) from“VBA-25” & Forest Management Zoning, shows that to date planning & zoning processes required by Vicforest & the Department of Environment, Land, Water and Planning (DELWP) have not identified the location of rare plant species or provided appropriate management & protection zones for Cyathea cunninghamii (Slender Tree‐ fern) throughout this area, leaving this species vulnerable to the effects of Vicforests scheduled logging operations. Vicforests operations have not complied with their obligations to conserve significant ecological values, including through application of the precautionary principle and implementation of mandatory management actions relevant to the potential population extent of rare and threatened species identified in the areas detailed within this report. Recommendations are made to the Department of Environment, Land, Water and Planning (DELWP) to pursue the requirements of the precautionary principle and the need to apply appropriate management zones within the study location and ensure that rare and threatened species throughout State Forest areas are not affected by the impact of Vicforest logging operations. Relevant Legislation: “Management Standards and Procedures for timber harvesting operations in Victoria’s State forests, 2014” (MSP's) “Planning Standards for timber harvesting operations in Victoria’s State forests 2014” (Planing Standards) “Code of Practice for Timber Production 2014” (Code) “East Gippsland Regional Forest Agreement” (RFA) “East Gippsland Forest Management Plan” (FMP) “Flora and Fauna Guarantee Act 1988” (FFGA) Status of Site: Vicforest Logging Coupes 827-513-0017, 827-515-0006 are currently on approved Vicforest TRP Scheduled, 827-515-0006 is listed as harvest pending on Vicforest THSZ website.

The Purpose of this investigating was to determine the presence of rare or threatened flora species & Communities, including Warm Temperate Rainforest (EVC32), Cyathea marcescens Skirted Tree-fern and FFGA listed species Cyathea cunninghamii Slender Tree-fern, within and adjacent to Vicforest clear-fell logging coupes 827-513-0017 & 827-515-0006. Both the hybrid Cyathea marcescens & the parent genus Cyathea cunninghamii were found in close proximity to planned Vicforest Logging operations, along with surrounding Warm Temperate Rainforest. Method: Date of investigation: 19/04/2016 – 13/07/2016 Site Assessments (walking throughout forested areas within and adjacent to coupes). Site visits were conducted into various areas likely to contain rainforest within and adjacent to Vicforest logging coupes 827-513-0017 & 827-515-0006, exploring the rainforest & rainforest margins for rare and threatened flora. As Rare or threatened flora species presence was documented and species location details and photographic records were obtained. Assessment of rainforest elements such as composition, distribution and disturbance severity of 2014 bushfire, was conducted throughout the site and with GIS spacial data & aerial imagery. For servilely burnt rainforest areas the “differential species approach” (Differential Species Keys for the Delineation of Rainforest Boundaries July 2011 ) along with aerial imagery pre-2014 bushfire, was used to ascertain the extent and boundary.

Ground and aerial assessed 2014 fire affected & non-fire affected Rainforest. • Warm Temperate Rainforest was encountered throughout each of the three gully systems bordering the two Vicforest logging coupes 827-513-0017 & 827-515-0006. The ground assessment of rainforest was based on the floristic composition, structural integrity following multiple disturbance history (logging & fire), and the distribution of rainforest throughout the site. The rainforest assessed using aerial imagery shown in Map 2. tries to best represent the extent these values based on a comparison of the aerial imagery covering known rainforest areas discovered on site with similar areas of contiguous and nearby forest shown in the aerial imagery. See Map2. • The integrity of rainforest in areas post the 2014 bushfire was assessed and where severely damaged rainforest was identified as having severe canopy damage or canopy removed completely, in this circumstance the “differential species approach” (Differential Species Keys for the Delineation of Rainforest Boundaries July 2011 ) was used to ascertain the boundary. This occurred within logging coupe 827-513-0017 along a section of the northern boundary. The extent of severely burnt rainforest areas out side of the coupes are ascertained by aerial imagery pre 2014 bushfire. See: Table 1. & Map2. Results 2.

  • A Taxonomic Revision of Hymenophyllaceae
    BLUMEA 51: 221–280 Published on 27 July 2006 http://dx.doi.org/10.3767/000651906X622210 A TAXONOMIC REVISION OF HYMENOPHYLLACEAE ATSUSHI EBIHARA1, 2, JEAN-YVES DUBUISSON3, KUNIO IWATSUKI4, SABINE HENNEQUIN3 & MOTOMI ITO1 SUMMARY A new classification of Hymenophyllaceae, consisting of nine genera (Hymenophyllum, Didymoglos- sum, Crepidomanes, Polyphlebium, Vandenboschia, Abrodictyum, Trichomanes, Cephalomanes and Callistopteris) is proposed. Every genus, subgenus and section chiefly corresponds to the mono- phyletic group elucidated in molecular phylogenetic analyses based on chloroplast sequences. Brief descriptions and keys to the higher taxa are given, and their representative members are enumerated, including some new combinations. Key words: filmy ferns, Hymenophyllaceae, Hymenophyllum, Trichomanes. INTRODUCTION The Hymenophyllaceae, or ‘filmy ferns’, is the largest basal family of leptosporangiate ferns and comprises around 600 species (Iwatsuki, 1990). Members are easily distin- guished by their usually single-cell-thick laminae, and the monophyly of the family has not been questioned. The intrafamilial classification of the family, on the other hand, is highly controversial – several fundamentally different classifications are used by indi- vidual researchers and/or areas. Traditionally, only two genera – Hymenophyllum with bivalved involucres and Trichomanes with tubular involucres – have been recognized in this family. This scheme was expanded by Morton (1968) who hierarchically placed many subgenera, sections and subsections under

Six floristic communities are described from rainforest in northern and eastern Tasmania. The communities occur in lower rainfall areas, where they are often restricted ro fire-protected sites. They have climatic envelopes which are significantly distinct from each other and from rainforest in higher rainfall areas. The conservation status of the communities is assessed. Key Words: rainforest, Tasmania, conservation, relicts.
