Talk:Invasive Non-Native Species

From OpenStreetMap Wiki
Jump to navigation Jump to search

With current (2014-03-05) basic tagging proposed, there's no way to know if a given OSM object is an Invasive Non-Native Species. Wouldn't it be good to add a tag to clearly mark the object as INNS? It would ease searches, thematic map creation, etc. 5 March 2014‎ Carluti

Agreed. I suggest INNS=Yes --Cordialement, gerdami 12:36, 27 April 2015 (UTC)

TagInfo invasive=* has been used a few times and is more meaningful than INNS. --Cordialement, gerdami 11:37, 15 September 2015 (UTC)

Confusion over the taxon tag

I have some confusion over the taxon tag. If you don't think too much about it, taxon seems to indicate taxonomy more than the INNS-ness of a tree. So, if I was marking an INNS tree, would I use the tag "taxon" instead of the tag "species"? Is that what the article is trying to say?Arunasank (talk) 16:03, 1 September 2015 (UTC)

Mapping Invasive Non-native Species is not recommended on OSM

This wiki page is very misleading, and I think was written by someone who was unfamiliar with general principles of OSM.

To summarise, the main objections:

  • Sites often ephemera. Locations of invasive species are likely to change. Many are opportunists (for instance there was a whole suite of plants which invaded London on bomb sites during and after WWII; and indeed before that after the Great Fire of 1666). Many species will be subject to active control measures so may not persist in prominent sites.
  • Many are herbs or waterweeds. We do not generally map any herbs (i.e, non-tree non-shrubs) anyway.
  • Better tools. There are a whole suite of apps, technologies & reporting tools more suited to this type of thing.
  • Ground truth. Some are very difficult to ground truth (e.g., infestations of Oak Promontory moths)

What can we map:

  • Permanent sites of long-lived non-native species: woods, planted and self-seeded trees, scrub & hedges dominated by non-native species (e.g. Fuchsia in Western Ireland). The usual tags for woods, scrub, hedge etc can be used with appropriate taxon or dominant_taxon tags.
  • Plant communities dominated by a non-native species. For instance the Sarracenia (Pitcher Plant) which grows on a bog in Ireland is visible as a distinct patch of different coloured vegetation on aerial imagery.
  • Other evidence is available. For instance in County Donegal there are roadside signs warning of the presence of Japanese Knotweed. Their intention is that workmen avoid strimming the verge and spreading the plant. In this case the warning sign can be mapped.

I intend to place a deprecaton note on this page, once I've assembled more avidence from discussions which have taken place over the past 10 years. SK53 (talk) 10:30, 17 May 2020 (UTC)
