Minyirr Park is an important part of Yawuru country and is known for its protection and healing qualities and is a sacred bilyurr (spirit) place for Yawuru people. Minyirr Park is identified as containing three of the nine Yawuru Habitats as defined in the Yawuru Cultural Management Plan (Yawuru RNTBC 2011) including; Niyamarri (Sand dunes), Bundurrbundurr (Pindan country), Mayingan manja balu (Vine thickets -lit. plenty fruit trees). Through the work of Yawuru Traditional Owners and other Aboriginal people, and with the support of local environmental groups such as the Broome Botanical Society, Minyirr Park was established in 1999 as a conservation reserve. For many years the park was managed by the Minyirr Park Rangers including Mickelo Corpus, Franz Hoogland and Richard Hunter through the Rubibi Aboriginal Land, Heritage and Development Council, and supported by the Shire of Broome (SOB) and the Kimberley Land Council (KLC). Later, in 2006 Yawuru people were recognised as Native Title Holders of the Broome area and surrounds and in 2010 entered into two Indigenous Land Use Agreements (ILUAs) with the WA State, the Shire of Broome and other Parties. This resulted in the creation of a Yawuru Conservation Estate (Figure 1) to be jointly managed by Yawuru, the Department of Biodiversity, Conservation and Attractions (DBCA, formally Department of Environment and Conservation) and the SOB. Minyirr Park falls within the Minyirr Buru Conservation Park(In-town Reserves) which is jointly managed by Yawuru and the SOB. The Yawuru Park Council, comprised of Yawuru and SOB representatives, is responsible for the management of the Minyirr Buru Conservation Park with assistance from DBCA. Figure 1.

Minyirr Park Weed Recommendations 2018 | 4 Habitats Monsoon Vine Thickets – Mayingan manja balu Mayingan manja balu (Vine thickets -lit. plenty fruit trees) and Niyamarri (Sand dunes) habitats in Minyirr Park are host to the ecosystem identified as Monsoon Vine Thickets on the coastal dunes of Dampier Peninsula. This ecosystem was recognised by the Federal Government as Endangered in 2013 (Environment Protection Biodiversity and Conservation Act 1999) due to the increasing degradation from land clearing, wildfire and weed invasion. Monsoon Vine Thickets (MVT) are scattered in a network of small and large patches from Broome north around the coast of the Dampier Peninsula and are one of the Kimberley's most endangered plant communities. The MVT are the most southern dry rainforest-type ecosystem in Western Australia, surviving so far south into the arid zone only because of the Peninsula’s hydrogeology leading to a shallow freshwater table at the coasts. MVT are ecologically significant, representing less than 0.01% of the Peninsula in area, yet containing 25% of the species as well as an array of rainforest-aligned animals. Although variable in size and distribution, patches of MVT are interconnected by frugivorous animals like bats and birds which play an important role in seed dispersal. Hence the protection of existing MVT are important not only in their own right but also as seed sources for neighbouring patches that may have been impacted. MVT are culturally important to Aboriginal groups throughout the region, containing a very high density of plants with useful properties (e.g. food, artefacts, medicine) and often contain restricted ceremony areas and law grounds. It is therefore important to liaise with Traditional Owners before entering or conducting any works within MVT. The MVT of Minyirr park lie in the swale and lee of the coastal dunes, transitioning into the pindan woodland habitat inland. The extent of MVT in Minyirr Park has reportedly decreased over the years, according to both anecdotal observations and comparisons with historical imagery from 1949 (Trudgen 1988). This has occurred due to clearing for development, weed infestation, altered hydrogeology and inappropriate fires including by the infamous Shire staff member “Smokey Bear“(1978-1982), who would burn the area as often as it would burn to stop illegal camping by Inside the Monsoon Vine Thicket Minyirr Park Weed Recommendations 2018 | 5 “hippies” (Trudgen 1988). The Minyirr MVT are some of the most southern on the Dampier Peninsula, containing less species than northern patches due to decreased rainfall (Black et al. 2010).

  • Monsoon Vine Thickets of the Dampier Peninsula a Summary of Key Findings from the Broome Botanical Society Introduction
    Monsoon Vine Thickets of the Dampier Peninsula A Summary of Key Findings from the Broome Botanical Society Introduction Australian rainforests are fragmented and have a limited range. In the Kimberley, there are only about 7000 hectares of rainforests, less than 0.0001% of the region, yet they contain around 25% of the Kimberley’s plant species. Monsoon vine thickets are just one of many different types Dampier Peninsula of rainforest in Australia, and the network of vine thickets on the Dampier Peninsula forms the southern limit of Derby rainforest in Western Australia. Broome Monsoon vine thickets are culturally significant for Traditional Owners. They are important sources of seasonal fruits and berries, yams, carving timber, Exmouth medicines and accessible ground water. Some vine thicket patches contain culturally sensitive law-grounds. In contrast to other Kimberley and Northern Australian monsoon vine thickets, the Dampier Peninsula’s monsoon vine thickets contain different arrangements of plants and are uniquely found behind and within the swales of coastal sand dunes. Vine thickets are not known to occur where the annual rainfall drops below 600mm. The trees and vines create a dense, shady and protective canopy and are more humid than the open woodlands around them. Monsoon vine thickets are a refuge for many plants and animals and despite only covering less than one tenth of one percent of the Dampier Peninsula they contain nearly a quarter of all plant species found here. Monsoon vine thicket plants depend on frugivorous (fruit-eating) birds, bats and wallabies eating and digesting the seeds and spreading them from one patch to the next.

  • Monsoon Vine Thickets on the Coastal Sand Dunes of the Dampier Peninsula
    INTERIM RECOVERY PLAN NO. 383 Monsoon vine thickets on the coastal sand dunes of the Dampier Peninsula 2018 – 2023 February 2018 1 Foreword Interim Recovery Plans (IRPs) are developed within the framework laid down in Department of Parks and Wildlife (now Biodiversity, Conservation and Attractions) Corporate Policy Statement No. 35 (DPaW 2015a) and Corporate Guideline No. 35 (DPaW 2015b). Corporate Policy Statement No. 35 states that the department will prepare recovery plans or conservation advices that document the conservation requirements, recovery or management actions and information requirements of threatened species and ecological communities (TECs), identify threatening processes impacting threatened species or TECs, and implement programs to mitigate the threats. Interim recovery plans outline the recovery actions that are required to urgently address those threatening processes most affecting the ongoing survival of threatened species or ecological communities, and begin the recovery process. While the Department of Biodiversity, Conservation and Attractions (DBCA) is committed to ensuring that threatened ecological communities are conserved through the preparation and implementation of Recovery Plans (RPs) or IRPs, there is no statutory requirement to implement recovery actions identified in this plan. This plan identifies responsibilities for specific actions and largely refers to the department initiating and guiding actions. However, the implementation of recovery actions by the Department of Biodiversity, Conservation and Attractions or any other organisation will be done within the context of regional and statewide priorities and technical and resource capacity. The provision of funds identified in this plan is dependent on budgetary and other constraints affecting the Department of Biodiversity, Conservation and Attractions, as well as the need to address other priorities.

  • The Coastal Habitats and Vegetation of the Kimberley Region
    Journal of the Royal Society of Western Australia, 94: 197–206, 2011 The coastal habitats and vegetation of the Kimberley region I D Cresswell 1, P Bridgewater 2 & V Semeniuk 3 1 CSIRO Wealth from Oceans Flagship, GPO Box 1538, Hobart, Tasmania, 7001 2 The Wharfside, Station Place, Peel, Isle of Man, British Isles 3 V & C Semeniuk Research Group, 21 Glenmere Rd., Warwick, W.A., 6024 Manuscript received March 2011; accepted April 2011 Abstract Incorporating the areas of the rocky Kimberley Coast, flanked by the deltaic gulfs of Cambridge Gulf and King Sound, as well as the Dampier Peninsula, the Kimberley region host a complicated coastal zone with a plethora of coastal habitats. The smallest scale of habitat includes rocky cliff, scree slopes, gravelly/bouldery shore, sandy beaches, spits, dunes, tidal mud flats, alluvial fans, and the contact between some of these habitats and freshwater. The main vegetation units include mangroves, shrubby chenopods (which include succulent halophytic shrubs), saline marsh, sedgelands, rushlands, dune scrub, dune grasslands, and teatree thickets. The spatially and temporally variable landscape, sediments/soils, and hydrochemistry expressed at the coast mean that the coastal vegetation habitats are the most complex habitats in the Kimberley region. This review found that to date these have not been fully explored or described botanically.

  • Bardi Plants an Annotated List of Plants and Their Use
    H.,c H'cst. /lust JIus lH8f), 12 (:J): :317-:359 BanE Plants: An Annotated List of Plants and Their Use by the Bardi Aborigines of Dampierland, in North-western Australia \!o\a Smith and .\rpad C. Kalotast Abstract This paper presents a descriptive list of the plants identified and used by the BarcE .\borigines of the Dampierland Peninsula, north~\q:stern Australia. It is not exhaust~ ive. The information is presented in two wavs. First is an alphabetical list of Bardi names including genera and species, use, collection number and references. Second is a list arranged alphabetically according to botanical genera and species, and including family and Bardi name. Previous ethnographic research in the region, vegetation communities and aspects of seasonality (I) and taxonomy arc des~ cribed in the Introduction. Introduction At the time of European colonisation of the south~west Kimberley in the mid­ nineteenth century, the Bardi Aborigines occupied the northern tip of the Dam­ pierland Peninsula. To their east lived the island-dwelling Djawi and to the south, the ~yulnyul. Traditionally, Bardi land ownership was based on identification with a particular named huru, translated as home, earth, ground or country. Forty-six bum have been identified (Robinson 1979: 189), and individually they were owned by members of a family tracing their ownership patrilineally, and known by the bum name. Collectively, the buru fall into four regions with names which are roughly equivalent to directions: South: Olonggong; North-west: Culargon; ~orth: Adiol and East: Baniol (Figure 1). These four directional terms bear a superficial resemblance to mainland subsection kinship patterns, in that people sometimes refer to themselves according to the direction in which their land lies, and indeed 'there are.

  • I Is the Sunda-Sahul Floristic Exchange Ongoing?
    Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared.

    KIMBERLEY TROPICAL MONSOON RAINFORESTS OF WESTERN AUSTRALIA: PERSPECTIVES ON BIOLOGICAL DIVERSITY Kevin F. Kenneally School of Agriculture & Environment, Faculty of Science The University of Western Australia, MOO4, 35 Stirling Highway Crawley, Western Australia 6009, AUSTRALIA Nulungu Research Institute, Notre Dame University Australia, Broome, Western Australia, AUSTRALIA Western Australian Herbarium, Department of Biodiversity Conservation and Attractions (DBCA), Locked Bag 104, Bentley Delivery Centre, Western Australia 6983, AUSTRALIA Western Australian Museum, Department of Terrestrial Zoology 49 Kew St, Welshpool, Western Australia 6106, AUSTRALIA [email protected] ABSTRACT There are more than 1,500 patches of monsoon rainforest, totaling 7,000 hectares, scattered across 170,000 square km of the tropical Kimberley region of Western Australia. They are small, isolated and embedded within a mosaic of mostly flammable eucalypt savanna woodlands. The status and condition of Kimberley monsoon rainforest biodiversity are assessed based on geographically comprehensive survey data from a total of 100 sites and opportunistic collecting in many others. Monsoon rainforests are rich in species not found in the region’s other vegetation communities. Most rainforests and their associated faunal assemblages are not currently reserved and many of the survey sites were found to be severely disturbed by fire and introduced feral cattle. The disturbance impact of fires, introduced animals and weeds is shown to apply generally across the three major forms of land tenure operating in the Kimberley; namely, Aboriginal land (includ- ing Indigenous Protected Areas), Crown land (including pastoral leasehold), and national parks and reserves. The implications of these disturbance factors on the conservation and management practices of monsoon rainforest patches in the region are considered.
