Ann Parkinson and Anne Harvey, two experienced\u00a0botanists and grass experts, surveyed the Millennium\u00a0Green grasses in five areas, as seen on the image above:\u00a0Improved Grassland, the Wet Area, the Scrub Area, the\u00a0Re-seeded Wild Flower Area and the Peninsula. They\u00a0identified and listed species of grass in order of\u00a0frequency in each of the areas\u00a0<\/p>\n

Their report is included here<\/a> and will be made available\u00a0along with illustrated grass identification folders at the\u00a0entrance to the Millennium Green for the benefit of\u00a0visitors and students.<\/p>\n

Grass identification as well as the identification of other\u00a0flora and fauna in the Millennium Green is expected to be\u00a0an on-going project.<\/p>\n

<\/a>Thorverton Millennium Green Grass Survey 13th May 2015-\u00ad-Summary<\/strong><\/p>\n

On 13th May 2015 two surveyors walked the Millennium Green and recorded the plant and grass species. The area was divided up into the main grassland area, wet area, scrub area, the peninsula and the re-seeded wild flower area. The hedges and boundaries have yet to be completed.<\/p>\n

The DAFOR scale was used, as it is a quick way of measuring the frequency of the
plants seen within a given area.<\/p>\n

The DAFOR scale comprises the following categories:<\/p>\n

Value
D -\u00ad Dominant 75% Rarely used in practice
A – Abundant 51-75% Very common over most of site
F – Frequent 26-50%
O -\u00ad Occasional 11-25%
R – Rare 1-10%<\/p>\n

It is generally recognised that recording plant cover using the DAFOR scale is extremely subjective.<\/p>\n

Notes<\/strong><\/p>\n

    \n
  1. If a species appears to be intermediate between two categories, it is generally assigned to the lower category, being affected by a number of factors and in particular recorder bias.<\/li>\n
  2. There are additional categories of LD, LA and LF, where L=locally<\/li>\n<\/ol>\n
