A WEEK in LA Palikia, CANARY ISLANDS, in Iw(*) 1 A WEEK IN LA PALikIA, CANARY ISLANDS, iN iW(*) (Recibilo e1 1O.VTII. 33) 9Y H.G. Allcard, F.R .%.S. (t)and Anthony Valletta,F.R.E.S Tn September 1931 ve visited La Palma for the first time and were impressed by the large nunber of Pirris cheiranthi Hbn.f .benchoavonsis pinker seen flying in the mountainous forestal ares of the northern part Of the island, añd as in suc'h a habitat nasturtium (Tropaeolum majus) ras norhere to be seen, ve wondered rhat the larval foodplant could be. We adchieved little on that risit as the dull aeather had limited our field rork to a fea hours. On this occasian, having elloied more time, le planned to discover the alternative food- plant in that island and also h3pe4 to come acrass the female of Conepteryx palmae Stamm. as re sar only fresh males in 1931 having Seen a bit early for the second brood. We left together from Cataick Airport on the morning of June the 8th and after a pieasant light arrived at Tenerife. There re changed plane and flea straight to La Palma, a short flight f only 20 minutes. We stayed as before at the San Miguel Hotel at Santa Cruz de La Palma. As t ras 5:15 p.m. ahen re got there, re could do nothing that day except have a drink and a rest n a bar and esJoy the fresh breeze blowing from the sea. 9th. June. Starting at 10 a.m. ae drove by taxi to the forestal area, climbing up to along the only road on the east coast. After over one hour's driving round many aakaard gerous bends, now going uphill then doanhill, noa through tunnels then over bridges, re at our destination. Along the road re saw quite a good number of Pieris rapae L. es- close to the cottages rhich at this time of the year had their gardens re11 set ríth of the season: glad ioli, hollyhocks, Madonna lilies, Begonia, Antirrhinum and Geraníum rent colours.

We had to wait ti11 12:20 to see P. cheiranthi coming don to the road from the aooded mountains high above. haa passed their best but's5me-of the females rere stíll quite fresh. Several Pararge xiphioides Staud. visited the floaers and a coupie of colias crocea Ceoffr. fler rapidly along bhe road; even here P. rapae ras out in large numbers. At 3:40 re had to pack up as clouds 'started to cover the area. 10th. June. Once more re tried the same locality but re stopped half ray for an hour &-clase- to Tunel de la Galga where many wild flowers aere blooming and laurel trees covered the erges of the barranco and the slopes of the mountain. Here re came across the first C. palmae, female feeding at the flowers of Rubus ulmifolius; it seemed that it had been on the ring for Ome time as it ras quite rorn. Manxolajurtinafortunata Alph. ras very common in the shaied egetation. The other species already mentioned were fairly common and in good condition exCept or the P. cheiranthi. We drove further up for the rest of the day. almae both males and emales, came our aay but this time it seemed that we rere late for bbrood. Here G- zpir;a vul cania God. and Pandoriana pandora D. 8 S., rere seen. k Beatlng the vegetation by the roadside to disturb microlepidoptera and other insects, re came across a plant with tiny ahite flowers and rhilst admiring its beauty our gaze fe11 on a well-bítten leaf. We put our nets and bags aside and started to search. Turning the leaf, to our great Joy and excitement re sar a cluster of tiny caterpillars and under another leaf a >'batch of yelloa eggs. Then close to the ground ae found almost fully grorn caterpillars which 'looked very much like those of Pieria braasicae L. As P. brassícae L. is not found in the Gcanaries re felt sure they rere the larvae of p. cheiranthi. We took a couple of leaves and ?a bract of floaers for the identification of tne plant. It turned out to be Crambe strigosa iL'H6r. (Cruciferae), a small shrub groring up to 1.5 m. hígh in the crevices and fissures of *the rocks as endemic plant. 11th. June. Thfs time re tried a different locality in the centre of the island - Mirator La Cumbrecita rhich is nearly 300 m. above sealevel. There was an extensive piantation Of PinUS Tanariensfs afth no vegetation growing underneath and there ras nothing flyfng about. le there- Crore took the road rhich leads to El Paso and stouued at a sDot rhich ras covered rith rild flor- -&sers. There re saw Lycaena phlaeas L., Aricia craiera Eschscholtz, P. rapae and C. crocea. Later 5-e stopped again by the side of a road named Buena Vista near Brena Alta rhere one could see a *.aost beautiful viea of a part of the east coast of the island. Liaht blue thistles covered a gfjgood part of the area. A number of butterflies rere visíting the fiowers and re could apot p. gCheiranthi, C. crocea including f. helicina Ob., L. phlaeas and M. jurtina f. fortunata. le stop- $sd further down at the old airport as on both siaes of the runray several plants rere being g'isited by butterflies. Here C. crocea and M. Jurtina rere plentiful, rhilst fresh Pontia da- %$!lidice L. and Thymelicus acteon christf Rb1. aere fairly common. T.. - - 12th. June. We took our earlier route to the north-east of the island as re considered - that as the best for lepidoptera. We stopped for a rhile beyond the Galga- Tunnel -as G.pa1- i :7*.)

Unfortunately there was no sun during the remaining two days, she did not feed and so she died. 13th. June. There was no sun al1 the day and nothing on the wind except P. rapae. 14th. June. The weather was even worse and it rained up to 2:OO p.m. As a last surprise we found a cluster of P. cheiranthi eggs on a small leaf of a wild cabbage plant. 15th. June. At 9:iO a.m. we flew to Tenerife; this time we landed at the old airport and, after paying a short visit to Dr. A. Machado to thank him personally for his help, we drove to the new airport to take the-plane back to Gatwick. Though we had to stay for five hours in Tenerife we could not do any collecting as it was anoti dull day. General remarks: Whilst P. cheiranthi is very localized in - Tenerife, being found at Puerto da la Cruz mostly in hotel gardens ~ and surrounding areas where nasturtium grows, in La Palma it is more widely distributed. We came across it al1 along the east coast from Los Sauces at the very top of the island down to the sea-front at the city of Santa Cruz. We were not after moths but we did not miss thosr that came our way. Beating the vegetation we disturbed the following Pyrales: Hymenia recurvalis Fabr ., ' Uresiphita limbalis D. & S ., ,Noma- phila noctuella D. & S .,Phiuche lividalis Hubn., Duponchelia fuvea- -lis Zell., Loxostege sulphuralis Hubn., .Mecyna asinalis Hubn., Sito- chroa paleaxs D. & S. and'rUdea ferrugalis Hubn. One evening whilst ae were having dinner at the Parador Hotel,; a Hawk-moth flew into the dining-room and after going round al1 the 1 lights rested on a curtain giving us the chance of identifying it as 1 Hyles lineata livornica Esp. Also on that evening, returning to our ; hotel we noticed the following Geometridae resting on the shop-windms: Cleora fortunata Black and Gymnoscelis rufifesciata Haw.

    Wildlife site resource map and species information for neighbourhood planning – Abbotskerswell June 2016 - 1 - Guidance notes: 1-Introduction Any development, from a loft conversion to a housing estate has the potential to affect wildlife. By wildlife we mean the whole range of plants and animals found in Devon (also referred to as biodiversity). Sites that are important for their geology can also be affected. With a Neighbourhood Plan, communities are able to establish general planning policies for the development and use of land in a neighbourhood. They will be able to say, for example, where new homes and offices should be built, and what they should look like. Neighbourhood Plans should take into account local need, housing targets identified by the local authority and the mitigation hierarchy. This is important, as where the local authority says that an area needs to grow, then communities can use neighbourhood planning to influence the type, design, location and mix of new development. They cannot however use neighbourhood planning to block the building of new homes and businesses. The information below is provided to assist you in designing a neighbourhood plan, however the information DBRC holds on biodiversity can be enhanced by additional survey or species recording within the area and you may want to consider how more information could be gathered by the community. For further information on how to record biodiversity where you live, go to http://www.dbrc.org.uk 2.1 Sites important for wildlife There are several designations that cover sites of wildlife and geological value in Devon. These include sites with international and national statutory designation and local non- statutory designation and are shown on your map.

  • South-Central England Regional Action Plan
    Butterfly Conservation South-Central England Regional Action Plan This action plan was produced in response to the Action for Butterflies project funded by WWF, EN, SNH and CCW by Dr Andy Barker, Mike Fuller & Bill Shreeves August 2000 Registered Office of Butterfly Conservation: Manor Yard, East Lulworth, Wareham, Dorset, BH20 5QP. Registered in England No. 2206468 Registered Charity No. 254937. Executive Summary This document sets out the 'Action Plan' for butterflies, moths and their habitats in South- Central England (Dorset, Hampshire, Isle of Wight & Wiltshire), for the period 2000- 2010. It has been produced by the three Branches of Butterfly Conservation within the region, in consultation with various other governmental and non-governmental organisations. Some of the aims and objectives will undoubtedly be achieved during this period, but some of the more fundamental challenges may well take much longer, and will probably continue for several decades. The main conservation priorities identified for the region are as follows: a) Species Protection ! To arrest the decline of all butterfly and moth species in South-Central region, with special emphasis on the 15 high priority and 6 medium priority butterfly species and the 37 high priority and 96 medium priority macro-moths. ! To seek opportunities to extend breeding areas, and connectivity of breeding areas, of high and medium priority butterflies and moths. b) Surveys, Monitoring & Research ! To undertake ecological research on those species for which existing knowledge is inadequate. Aim to publish findings of research. ! To continue the high level of butterfly transect monitoring, and to develop a programme of survey work and monitoring for the high and medium priority moths.

  • Maritime Cliffs and Slopes Habitat Action Plan (Revised)
    Maritime Cliffs and Slopes Habitat Action Plan (Revised) Isle of Wight Biodiversity Action Plan Maritime Cliffs and Slopes Habitat Action Plan Second Review December 2007 1 Introduction Maritime cliffs and slopes have been identified as a priority habitat in the UK Biodiversity Action Plan. They comprise sloping to vertical surfaces on the coastline where a break of slope is formed by slippage and/or coastal erosion. There appears to be no generally accepted definition of the minimum height or angle of slope which constitutes a cliff, but the zone defined as cliff top should extend landward to at least the limit of maritime influence (i.e. limit of salt spray deposition). On the seaward side, the plan extends to the limit of the supralittoral zone and so includes the splash zone lichens and other species of this habitat. They can broadly be classified as hard cliffs or soft cliffs, though there are intermediate types. Hard cliffs are vertical or steeply sloping, with crevices or ledges where plants can establish themselves and birds can find nest sites. They are formed of rocks which are relatively resistant to weathering, such as chalk. Soft cliffs are formed in less resistant rocks such as shales or in unconsolidated materials such as boulder clay. They are characterised by less steep slopes that gradually become vegetated. They are subject to frequent slumping and landslips, particularly where water percolates into the rock and reduces its effective shear strength. Most cliffs form at the junction of land and sea, where groundwater-driven land slippage and/or erosion by the sea have created a break in slope, but on the Isle of Wight there is also an extensive landslip zone between St Catherine’s Point and Bonchurch which has an inner cliff 500m inland rising to 140m above sea level.

    Lepidoptera recorded at the RSPB's Arne Nature Reserve, Wareham, Dorset 1970 - 95 Bryan P Pickess & C James Cadbury January 2008 Reserves Ecology, RSPB, The Lodge, Sandy, Bedfordshire SG19 2DL wpo/dptshare/James Cadbury/Lepidoptera of a Dorset Heathland LEPIDOPTERA RECORDED AT THE RSPB'S ARNE NATURE RESERVE, WAREHAM, DORSET, 1970 – 95. By Bryan P. Pickess, 8 Shaw Drive, Sandford, Wareham, Dorset BH20 5BT C. James Cadbury, 93 Barton Road, Cambridge, CB3 9LL Summary This paper presents the results of Lepidoptera recording at the RSPB's Arne Nature Reserve, on the Purbeck Heaths of southeast Dorset, during the years 1970 – 1995. Most of the records resulted from moth trapping using a variety of lights close to the hamlet of Arne by Bryan Pickess, but sightings of butterflies and day-flying moths are included. Lowland heathland is the predominant habitat of the 501 ha reserve. A total of 34 butterfly species, 430 'macro'-moths and 366 'micros' have been recorded at Arne. They include 10 Red Data and 34 Nationally Notable 'macro'-moths. Among the 'micros' are eight potential Red Data and 27 Nationally Notable species. Of particular conservation importance among the resident heathland species are the Dingy Mocha Cyclophora pendularia, Large Bagworm Pachythelia villosella, (a psychid,) and the plume Buckleria paludum, (Small Grass Emerald Chlorissa viridata, Bordered Grey Selidosema brunnearia Ringed Carpet Cleora cinctari). The BAP Priority Silver-studded Blue Plebeius argus (a Biodiversity Acha Plan Priority Species) has many colonies on the damper heathland. The Horse Chestnut Pachycnemia hippocastanaria (Nb) can be one of the most abundant moths on the heathland.

  • Folkestone and Hythe Birds Tetrad Guide: TR23 P (Capel-Le-Ferne and Folkestone Warren East)
    Folkestone and Hythe Birds Tetrad Guide: TR23 P (Capel-le-Ferne and Folkestone Warren East) The cliff-top provides an excellent vantage point for monitoring visual migration and has been well-watched by Dale Gibson, Ian Roberts and others since 1991. The first promontory to the east of the Cliff-top Café is easily accessible and affords fantastic views along the cliffs and over the Warren. The elevated postion can enable eye-level views of arriving raptors which often use air currents over the Warren to gain height before continuing inland. A Rough-legged Buzzard, three Black Kites, three Montagu’s Harriers and numerous Honey Buzzards, Red Kites, Marsh Harriers and Ospreys have been recorded. It is also perfect for watching arriving swifts and hirundines which may pause to feed over the Warren. Alpine Swift has occurred on three occasions and no less than nine Red- rumped Swallows have been logged here. Looking west from near the Cliff-top Café towards Copt Point and Folkestone Looking east from near the Cliff-top Café towards Abbotscliffe The Warren below the Cliff-top Café Looking west from the bottom of the zigzag path Visual passage will also comprise Sky Larks, Starlings, thrushes, wagtails, pipits, finches and buntings in season, whilst scarcities have included Tawny Pipit, Golden Oriole, Serin, Hawfinch and Snow Bunting. Other oddities have included Purple Heron, Short-eared Owl, Little Ringed Plover, Ruff and Ring-necked Parakeet, whilst in June 1992 a Common Rosefinch was seen on the cliff edge. Below the Cliff-top Café there is a zigzag path leading down into the Warren.
