California's Native Ferns
CALIFORNIA’S NATIVE FERNS A survey of our most common ferns and fern relatives Native ferns come in many sizes and live in many habitats • Besides living in shady woodlands and forests, ferns occur in ponds, by streams, in vernal pools, in rock outcrops, and even in desert mountains • Ferns are identified by producing fiddleheads, the new coiled up fronds, in spring, and • Spring from underground stems called rhizomes, and • Produce spores on the backside of fronds in spore sacs, arranged in clusters called sori (singular sorus) Although ferns belong to families just like other plants, the families are often difficult to identify • Families include the brake-fern family (Pteridaceae), the polypody family (Polypodiaceae), the wood fern family (Dryopteridaceae), the blechnum fern family (Blechnaceae), and several others • We’ll study ferns according to their habitat, starting with species that live in shaded places, then moving on to rock ferns, and finally water ferns Ferns from moist shade such as redwood forests are sometimes evergreen, but also often winter dormant. Here you see the evergreen sword fern Polystichum munitum Note that sword fern has once-divided fronds. Other features include swordlike pinnae and round sori Sword fern forms a handsome coarse ground cover under redwoods and other coastal conifers A sword fern relative, Dudley’s shield fern (Polystichum dudleyi) differs by having twice-divided pinnae. Details of the sori are similar to sword fern Deer fern, Blechnum spicant, is a smaller fern than sword fern, living in constantly moist habitats Deer fern is identified by having separate and different looking sterile fronds and fertile fronds as seen in the previous image. -
Iucn Summary Gough Island (United Kingdom) 2
WORLD HERITAGE NOMINATION - IUCN SUMMARY GOUGH ISLAND (UNITED KINGDOM) Summary prepared by IUCN/WCMC (March 1995) based on the original nomination supplied by the Government of the United Kingdom. This original and all documents in support of this nomination will be available for consultation at the meetings of the Bureau and the Committee. 1. LOCATION Located southeast of Tristan da Cunha Island in the south Atlantic Ocean, midway between Africa and South America. 2. JURIDICAL DATA The island and surrounding territorial waters were designated a wildlife area in 1976 under the Tristan da Cunha Conservation Ordinance. 3. IDENTIFICATION The island of Gough (6500ha) represents the eroded core of a Late Tertiary volcano. The east side of the island is dissected by a series of deep steep-sided valleys, which are separated by narrow serrated ridges. Along the west side of the island, rounded slopes extend from the central plateau to the western sea cliffs. Many offshore stacks and rocks are present, mostly within 100m of the main island. Vegetation comprises tussock grass around the coast and wet heath with moss and feldmark, and bog and swamp communities at higher elevations. Knowledge of the flora is incomplete but consists of some 35 native flowering plant and 28 native fern species. Over 30 of Gough's vascular plant taxa are endemic to the Tristan de Cunha islands. A total of 146 bryophytes have been recorded, eight of which are endemic, together with 20 fungi and 24 lichens. Invertebrate fauna also remains poorly known, but comprises 100 species, eight of which are endemic. -

Compared to seed plants, the diversity patterns of ferns have been poorly studied along disturbance gradients, including aspects of their taxonomic, phylogenetic, and functional diversity. Longnan County, a biodiversity hotspot in the subtropical zone in South China, was selected to obtain a more thorough picture of the fern–disturbance relationship, in particular, the taxonomic, phylogenetic, and functional diversity of ferns at different levels of disturbance. In 90 sample plots of 5 5 m2 along roadsides × at three sites, we recorded a total of 20 families, 50 genera, and 99 species of ferns, as well as 9759 individual ferns. The sample coverage curve indicated that the sampling effort was sufficient for biodiversity analysis. In general, the taxonomic, phylogenetic, and functional diversity measured by Hill numbers of order q = 0–3 indicated that the fern diversity in Longnan County was largely influenced by the level of human disturbance, which supports the ‘increasing disturbance hypothesis’. -

New Zealand Sub-Antarctic Islands New Zealand
NEW ZEALAND SUB-ANTARCTIC ISLANDS NEW ZEALAND The New Zealand Sub-Antarctic Islands consist of five remote and windswept island groups in the Southern Ocean south and south-east of New Zealand. The islands, lying between the Antarctic and Subtropical Convergences, are oases of high productivity, biodiversity, dense populations and endemism for birds, ocean life, plants and invertebrates. Of the 126 species of birds, 40 are seabirds of which 5 breed nowhere else in the world. They have among the most southerly forests in the world, an unusual flora of megaherbs and some small islands never colonised by man. COUNTRY New Zealand NAME New Zealand Sub-Antarctic Islands NATURAL WORLD HERITAGE SERIAL SITE 1998: Inscribed on the World Heritage List under Natural Criteria ix and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE [pending] The UNESCO World Heritage Committee issued the following statement at the time of inscription: Justification for Inscription Criterion (ix): The New Zealand Sub-Antarctic Islands display a pattern of immigration of species, diversifications and emergent endemism, offering particularly good opportunities for research into the dynamics of island ecology. Criterion (x): The New Zealand Sub-Antarctic Islands are remarkable for their high level of biodiversity, population densities,and for endemism in birds, plants and invertebrates. The bird and plant life, especially the endemic albatrosses, cormorants, landbirds and “megaherbs” are unique to the islands. IUCN MANAGEMENT CATEGORY Auckland Islands National Nature Reserve -

Heard and Mcdonald Islands Australia
HEARD AND MCDONALD ISLANDS AUSTRALIA Heard Island and the McDonald Islands are in the Southern Ocean, approximately 4,100 km south- west of Perth and 1,700 km from the Antarctic continent. Their distinctive conservation value is as one of the world’s rare pristine island ecosystems which have virtually no record of alien species and minimal human impact; also as the only volcanically active subantarctic islands they provide a window into ongoing tectonic activity, geomorphic processes and glacial dynamics. COUNTRY Australia NAME Heard and McDonald Islands NATURAL WORLD HERITAGE SERIAL SITE 1997: Inscribed on the World Heritage List under Natural Criteria viii and ix. STATEMENT OF OUTSTANDING UNIVERSAL VALUE [pending] The UNESCO World Heritage Committee issued the following statement at the time of inscription: Justification for Inscription The Committee inscribed this property under criteria (viii) and (ix). It noted that this site is the only volcanically active sub-Antarctic island and illustrates ongoing geomorphic processes and glacial dynamics in the coastal and submarine environment and sub-Antarctic flora and fauna, with no record of alien species. The Committee repeated its request by the sixteenth session for further documentation on the marine resources of the site.

Blechnum Spicant Joe Sime
THE NEWSLETTER OF THE SHADE AND WOODLAND PLANTS GROUP February 2019 Plant of the Month: Blechnum spicant Joe Sime It is at this time of the year when the truly evergreen ferns come into their own, and one of the best of these is Blechnum spicant. This is a widespread species occurring in western North America, N.E. Asia and Europe. It is known as the deer fern or the hard fern. Like other members of the genus it produces two types of fronds: low growing, green sterile fronds about 18 ins long that form a bright mat at this time of the year and are shown in the photo, and taller (up to 3 ft) upright, fertile fronds growing from the centre of the clump. Once the spores are cast in early autumn these die back, and can be trimmed off if you are a tidy gardener. It is a trouble free plant accepting any spot in full or part shade, although it would like some moisture occasionally. The one shown is by a path at the foot of a young oak tree. They are said to divide easily (I have not tried) and to grow quite well from spore. And if you are hungry, the North American Indians used to eat the roots and make tea from the fronds! Epimedium (a love affair!) Colin Moat It’s always quite interesting when putting together a piece like this to hark back to when you first became attracted to the plant you are writing about. It happened probably more than 20 years ago at a plant fair, and I was wowed by seeing a fabulous display offered by Europa Nursery (then based in London but they moved to Devon, and, I believe, closed their nursery).
