We suggest a method of constructing red numbers for plant species, in order to set priorities in con- servation policy. The red number is an additive index, summarising values of four parameters: 1. Rarity – The number of sites (1 km2) where the species is present. A rare species is defined when present in 0.5% of the area or less. 2. Declining rate and habitat vulnerability – Evaluate the decreasing rate in the number of sites and/or the destruction probability of the habitat. 3. Attractivity – the flower size and the probability of cutting or exploitation of the plant. 4. Distribution type – scoring endemic species and peripheral populations. The plant species of Israel were scored for the parameters of the red number. Three hundred and seventy (370) species, 16.15% of the Israeli flora entered into the “Red List” received red numbers above 6. “Post Mortem” analysis for the 34 extinct species of Israel revealed an average red number of 8.7, significantly higher than the average of the current red list.

  • Signalling and Beacon Sites in Dorset

    Signalling and Beacon Sites in Dorset

    THE DORSET DIGGER THE NEWSLETTER OF THE DORSET DIGGERS COMMUNITY ARCHAEOLOGY GROUP No 43 December 2016 Signalling and Beacon Sites in Dorset Richard Hood has kicked off this new project. He needs somemorevolunteerstohelpwith the research Introduction The ability to send or receive a message over a distance to warn of impending attack has been used to mobilise troops for defence since the Roman times. The Romans developed a system using five flags or torches to carry a simple message over short distances. This was usually used in battle to pass information out to army commanders. To carry a simple message further, a bonfire was used set on a high point, usually from a mini fort within vision of one or more other sites. This type of warning system was used during the invasion of Britain, when vexation forts could come under attack from tribes yet to be persuaded of the advantages of Roman living. Near the end of the Roman occupation signal stations were employed on the East and South coasts to warn of Saxon pirates. Roman signal stations on the NE coast of England took the form of mini forts, with a ditch and bank for defence. Black Down in Dorset, excavated by Bill Putnam and re examined by Dorset Diggers in 2016 is of this type. The Saxons appear to have had a system of inter divisible beacon sites to warn of Viking attack from the ninth century onwards. Later, beacons were erected to warn of the approach of the Spanish Armada, followed by a similar, but unused system, to warn of Napoleonic invasion.
