KiEco Freshwater Ecology: River Macrophytes - Geospatial
KiECO Ecoleg Dŵr Croyw Macroffytau Afonydd

  • English
  • wel
  • All

Macrophytes (water plants visible to the naked eye) can indicate the impact of pressures such as increased nutrients, flow pressures, channel alterations etc. The species present and their abundance give an indication as to the health of a river.


This dataset is made up of site information, sample metrics and taxa details for each survey conducted across Wales by Natural Resources Wales and former Environment Agency Wales since 1993. These surveys are conducted as part of on-going monitoring of river water quality for legislative requirements and to meet business drivers.

Mae macroffytau (planhigion dŵr sy’n weladwy i’r llygad noeth) yn gallu dynodi effaith pwysau fel mwy o faetholion, pwysau llif, newidiadau sianel ac ati. Mae'r rhywogaethau sy'n bresennol a'u helaethrwydd yn rhoi arwydd i ni am iechyd afon. Mae’r set ddata hon yn cynnwys gwybodaeth safle, metrigau sampl a manylion tacsonau ar gyfer pob arolwg a gynhaliwyd ledled Cymru gan Cyfoeth Naturiol Cymru ac Asiantaeth yr Amgylchedd Cymru gynt ers 1993. Mae'r arolygon hyn yn cael eu cynnal fel rhan o'r gwaith parhaus o fonitro ansawdd dŵr afonydd ar gyfer gofynion deddfwriaethol ac i fodloni ysgogwyr busnes.

Datganiad

A strict methodology is applied when sampling for freshwater macrophytes. There is a core network of sites which are monitoring on a three-year rolling programme. These sites are added to for investigative work, or on an ad hoc basis. Sampling areas are located with a larger survey area and must be representative of the overall survey area. A standard cover-class method is the most commonly used method for sampling freshwater macrophytes. Macrophyte species are identified on site and confirmed in the laboratory if necessary.


Redactions

Some information has be redacted to make the data openly available. This includes:

- Third party data

- Data collected for ongoing investigations

- Cancelled or incomplete surveys

- Taxa that falls within NRWs policy on Ecological data exempt from general release.


Update Frequency

This data is continually updated with the most surveys undertaken in the summer period (June to September). Data from survey seasons is entered as soon as possible following the surveys. The external dataset is updated monthly to include new data, and may also contain corrections to previously published data due to quality assurance work.


Information Warnings

We do our best to avoid data quality problems, but as these datasets reflect the data we hold, they may contain errors

The data is provided as a set of related data tables due to the quantity and structure of the data. A basic understanding of ecology and relational data is assumed.


Data related to pollution incident investigations or protected species information is not released as locational information of these sites may be detrimental to ongoing investigations or species protection.

Defnyddir methodoleg gaeth wrth samplu am facroffytau dŵr croyw. Mae rhwydwaith craidd o safleoedd sy'n cael eu monitro ar raglen dreigl tair blynedd. Ychwanegir at y safleoedd hyn ar gyfer gwaith ymchwiliol, neu ar sail ad hoc. Mae ardaloedd samplu wedi'u lleoli gydag ardal arolwg fwy ac mae'n rhaid iddynt fod yn gynrychioliadol o'r ardal arolwg gyffredinol. Dull dosbarthu cyffredin safonol yw'r dull a ddefnyddir amlaf ar gyfer samplu macroffytau dŵr croyw. Nodir rhywogaethau macroffytau ar y safle a'u cadarnhau yn y labordy os oes angen.


Golygiadau

Mae rhywfaint o wybodaeth wedi’i golygu i sicrhau bod y data ar gael yn agored. Mae hyn yn cynnwys:


Data trydydd parti

Data a gasglwyd ar gyfer ymchwiliadau parhaus

Arolygon wedi’u canslo neu heb eu cwblhau

Tacsonau sy'n dod o fewn polisi CNC ar ddata ecolegol sydd wedi'i eithrio rhag ei ryddhau'n gyffredinol

Amlder Diweddaru

Mae'r data hwn yn cael ei ddiweddaru'n barhaus ac mae'r nifer fwyaf o arolygon yn cael eu cynnal yn ystod cyfnod yr haf (mis Mehefin i fis Medi). Mae data o dymhorau arolygon yn cael ei fewnbynnu i system KiECO cyn gynted â phosibl ar ôl yr arolygon. Mae'r set ddata allanol yn cael ei diweddaru'n fisol i gynnwys data newydd, a gall hefyd gynnwys cywiriadau i ddata a gyhoeddwyd yn flaenorol oherwydd gwaith sicrhau ansawdd.


Rhybuddion Gwybodaeth

Gwnawn ein gorau i osgoi problemau ansawdd data, ond gan fod y setiau data hyn yn adlewyrchu’r data sydd gennym, gallant gynnwys gwallau.

Darperir y data fel set o dablau data cysylltiedig oherwydd maint a strwythur y data. Tybir bod dealltwriaeth sylfaenol o ecoleg a data perthynol yn bodoli.

Nid yw'r data sy'n ymwneud ag ymchwiliadau i achosion o lygredd neu wybodaeth am rywogaethau a warchodir yn cael ei ryddhau oherwydd gallai gwybodaeth am leoliad y safleoedd hyn fod yn niweidiol i ymchwiliadau parhaus neu waith gwarchod rhywogaethau parhaus.
