Statement

Riparian woodland in Scotland identified using a combination of existing open datasets. Search area is 20m either side of water courses. Includes coniferous and broadleaved woodland, native and non-native.

Search area created by buffering combined river dataset by 20m.

Woodland dataset created by clipping input woodland datasets to buffered area and merging output. Minimum patch size 2000m2.

Woodland datasets include Native Woodland Survey of Scotland, Smallwoods dataset from Forest Research, National Forest Inventory. Additional areas are included where these had been highlighted using height data and manually checked in aerial imagery.

Underlying water courses are OS open rivers, Vector Map District , SEPA open rivers, Open Street Map water courses. All are line datasets apart from Vector Map District which is a polygon dataset. Therefore the width of wider rivers has been taken into account (i.e. those that have been included in the VMD dataset).

Additional Details:

NFI (national forest inventory) : Categories included were : IFT_IOA = Assumed woodland, Broadleaved, Coppice, Conifer, Mixed mainly broadleaved, Mixed mainly conifer, Young trees.

Smallwoods dataset : Cloud/Shadow and felled categories are not included.

Native woodland survey of Scotland (split into two sources based on the ‘Type’ field. This field has 4 values : Native woodland, Nearly-native woodland, PAWS, and Open land habitat. Open land habitat was excluded. PAWS is included as a category (NWSS_PAWS), Native woodland and Nearly-native woodland were combined (NWSS_native_nearly_native)

Additional areas of woodland were included where these were identified of being above 2.5m and a manual check against aerial imagery suggested these were woodland. Nextmap height dataset was used. Areas included where at least 20% canopy cover (in line with NWSS) according to getmapping aerial imagery (most recent available in 2023, should be maximum 4 years old).

Fields:

The source of the woodland data is in the following fields, Nextmap (Nextmap = Nextmap), Smallwood (Smallwood = Smallwood), NWSS_PAWS (NWSS_PAWS=NWSS_PAWS), NWSS_native_nearly_native(NWSS_native_nearly_natve = NWSS_native_nearly_natve ), NF__2020 (NF__2020 = NFI). Associated attributes are to the left of the source fields. Note if multiple sources, information is retained from all sources.

IFT: related to Smallwood: C Conifer Coniferous woodland often occurs as large plantations with trees in

regular rows and the stand edges may be regular and sharply

defined. Some broadleaved trees may also be present but greater

than 80% of the area will consist of conifers.

B Broadleaved The canopy of broadleaved woodland is generally more uneven

than that of coniferous woodland being made up of rounded crowns

but with variations according to species, age, height, and season.

Boundaries with adjacent internal polygons are generally less

clearly defined than with conifers and naturally occurring stands

may grade into adjacent ones with no sharp division. Some

coniferous trees may be present but greater than 80% of the area

will consist of broadleaved trees.

Mc Mixed Predominantly Conifer Mixed woodland exhibits intermediate characteristics between

Conifer and Broadleaved woodland. There can be several types of mixed woodland. A plantation of alternate rows of conifer and broadleaves may produce a ‘striped’ appearance. You may see conifer and broadleaves planted in blocks, and there may be general intersperse woodland. The proportion of the Conifer will be more than 50% of the area and less than 80%.

Mb Mixed Predominantly Broadleaved Mixed woodland exhibits intermediate characteristics between Conifer and Broadleaved woodland. There can be several types of mixed woodland. A plantation of alternate rows of conifer and broadleaves may produce a ‘striped’ appearance. You may see conifer and broadleaves planted in blocks, and there may be general intersperse woodland. The proportion of the Broadleaves will be more than 50% of the area and less than 80%.

O Coppice The most important characteristic of coppice areas on aerial photographs is the very even, smooth appearance. The coppice area may be made up of a patchwork of different ages (heights) but all show this very even character. Areas recently cut may appear to have a very clear floor with little felling debris. Coppice is always of broadleaved trees.

P Coppice with Standards

Some areas of coppice also include larger broadleaved trees set in the coppice matrix. These broadleaved trees, often oak, are known as standards and show very clearly over the even coppice as large rounded crowns. The distribution of the standards may also be fairly scattered with approximately 25 per ha.

S Shrub Land This category is intended to include areas that may possibly be woodland, where the growth is close to the ground and shows a rough character but no clear differentiation between Conifer and Broadleaved can yet be made. Areas being colonised by woody species may fall into this category. The cover will be at least 20%.

N Young Trees Areas where planting is clearly visible but the trees cannot yet be allocated between Conifer and Broadleaved due to their immaturity. These areas can be on either land new to woodland or where a felled crop has been replaced.

G Ground Prepared forNew Planting

Very difficult to differentiate from agriculture, but may show plough furrows, spaced earth mounds or weed killed patches or strips as part of a new woodland regime. Likely to be part of an approved grant scheme held on G&L databases.
