Wiki Education assignment: Applied Plant Ecology Winter 2022

This article was the subject of a Wiki Education Foundation-supported course assignment, between 10 January 2022 and 23 April 2022. Further details are available on the course page. Student editor(s): Betonicifolia, Raizach (article contribs).

Removed long list on threats from IUCN

I've removed this list as it's not overly helpful for the readers. It also overlaps with the list that is provided just above in the same section. Also, the source provided doesn't show this list. Also, "threats to conservation" is not necessarily the same as "causes for biodiversity loss".

According to the IUCN the main direct threats to conservation fall in eleven categories:^[1]

Residential & commercial development: housing & urban areas, commercial & industrial areas, tourism & recreational areas
Farming activities: agriculture, aquaculture
Energy production and mining: renewable energy production, including hydroelectric dams, non-renewable energy production (oil and gas drilling), mining (fuel and minerals)
Transportation & service corridors: service corridors (for example electrical & phone wires, oil & gas pipelines), transport corridors (roads, railroads, shipping lanes, and flight paths), collisions with the vehicles using the corridors, associated accidents and catastrophes (oil spills, electrocution, fire)
Biological resource usages: hunting, persecution (predator control and pest control, superstitions), plant destruction or removal (human consumption, free-range livestock foraging), logging or wood harvesting, fishing
Human intrusions & activities that alter, destroy, disturb habitats and species from exhibiting natural behaviors: recreational activities, war, civil unrest, & military exercises, illegal activities (smuggling, vandalism), newly built housing
Natural system modifications: fire suppression or creation, water management (for example dam construction, groundwater pumping), other modifications (for example land reclamation), removing/reducing human maintenance (for example lack of indigenous management of key ecosystems, ceasing supplemental feeding of condors)
Invasive & problematic species, pathogens & genes: invasive species, problematic native species, introduced genetic material (for example pesticide-resistant crops, genetically modified insects for biocontrol), pathogens & microbes
Pollution: sewage, military & industrial effluents, forestry and agricultural effluents, garbage & solid waste, air-borne pollutants, excess energy (for example noise pollution and heat pollution)
Catastrophic geological events (natural hazards): earthquakes, tsunamis, avalanches, landslides, & volcanic eruptions and gas emissions
Effects of climate change: ecosystem encroachment (for example inundation of shoreline ecosystems & drowning of coral reefs from sea level rise), changes in geochemical regimes (for example ocean acidification), changes in temperature regimes (for example heat waves, marine heatwaves), changes in precipitation & hydrological regimes, severe weather events.

Added links and excerpts to articles on birds, flowering plants etc.

I've now added links and excerpts to the articles on bird, flowering plant, decline in wild mammal populations etc. I am a bit worried that eventually, this will bloat the article up too much and mean too many excerpts. But for now I do think it's important to point readers to the relevant other articles. This was based on suggestions by User:InformationToKnowledge, when we discussed the articles effect of climate change on plant biodiversity and effects of climate change on ecosystems. What are your thoughts about it now, I2K - does it work the way I've done it?

I wonder about one thing: the related decline articles, i.e. Decline in amphibian populations, Decline in wild mammal populations, Decline in insect populations , are not specifically about decline of diversity but could just be about decline in total numbers. E.g. if you split a very large wildlife area into two, and flatten the one half but leave the other half intact, then the total number of wildlife was halved but the biodiversity (number of species) might have stayed the same.

Should we therefore explain somewhere in this article how a decline in populations usually (but not always?) also means a decline in biodiversity? EMsmile (talk) 10:34, 5 February 2024 (UTC)[reply]

Simplify sentence on conservation efforts?

I think this sentence ought to be simplified, perhaps broken into two. It is using quite a bit of jargon and not very clear for our target group. I mark in bold what I find unclear: As of 2022 at least 64 million square kilometers (24.7 million square miles)—44% of terrestrial area—require conservation attention (ranging from protected areas to land-use policies) in order to secure important biodiversity areas, ecologically intact areas, and optimal locations for representation of species ranges and ecoregions.. I actually question if this sentence adds much value here or might be better off in the article on nature conservation, or a similar one. Pinging USer:RCraig09 as you had added this content. EMsmile (talk) 12:32, 6 February 2024 (UTC)[reply]

I've simplified the language, which is definitely appropriate in its /* Land use intensification */ section. The content may also be appropriate content in other articles in the See also hatnote in that section. —RCraig09 (talk) 17:59, 6 February 2024 (UTC)[reply]

Thanks, that sentence is a lot easier to understand now. EMsmile (talk) 21:30, 6 February 2024 (UTC)[reply]
