INTRODUCTION
This report will endeavour to introduce the International Union for Conservation of Nature and Natural Resources (IUCN) and the IUCN Red List they established to identify the species in danger of extinction in the world and the threats that they face while also being a tool for conservation action. It will then examine the threats to species in Ireland as per the IUCN Red List, identify which are the major threats for Ireland and suggest what areas to focus conservation actions on.
IUCN
The first International organisation established with the protection of Nature in mind, in 1922, was the establishment of the International Council for Bird Preservation and later renamed Birdlife (Holdgate, 2013). Then the International Union for the Conservation of Nature and Natural Resources (IUPN) was established in 1948 with the backing of the United Nations Educational, Scientific and Cultural Organisation (UNESCO) with very few resources and was initially set up as a meeting space and support for its members rather than an agency (Holdgate, 2013). It aimed to share information among members and in that way make a strong nature conservation movement. It later became the International Union for Conservation of Nature and Natural Resources (IUCN), sometimes referred to as the World Conservation Union (Holdgate, 2013). The IUCN is a unique entity in that the purpose of advancing sustainable development with the hope of creating a just world that conserves and values nature has given this institution the important role of bringing governments and civil society together with one purpose (Our Union, 2022). It has over 1,400 Member Organisations spanning States, government agencies, NGOs, scientific and academic institutions, indigenous groups, and businesses. Over 15,000 scientists and experts, in the UCN expert Commissions, provide knowledge and policy advice to its members (Our Union, 2022).
IUCN REDLIST
The IUCN Red List of Threatened Species was established in 1964(The IUCN Red List of Threatened Species, 2022). It is more than a databank of species, it is the information source on the global extinction risk of these species which include animal, fungus, and plant species (The IUCN Red List of Threatened Species, 2022). It is a critical indicator of biodiversity health and a powerful tool for change in policy and conservation action and is used across the globe by governments, NGO’s, environmental groups, educational organisations, business communities, and more to monitor population size and range, habitat and ecology and threats, actual and possible actions (The IUCN Red List of Threatened Species, 2022). It is compiled by the IUCN Global Species Program staff, experts, and organisations in the IUCN Species Survival Commission and partner networks (The IUCN Red List of Threatened Species, 2022). The aim is to create a more complete ‘Barometer of Life’, increasing the number of species assessed to at least 160,000 in order to assist the world in reversing the decline in biodiversity (The IUCN Red List of Threatened Species, 2022).
IUCN REDLIST IRELAND
The IUCN provide guidelines to produce RED lists at regional level and Ireland has
adopted these guidelines (Publications – Red Lists, 2022). The National Biodiversity Data Centre (NBDC) has also published a national standard for producing Ireland’s Red Lists. These lists are prepared with the guidance of the National Parks and Wildlife Service (NPWS) in the Republic and the Northern Ireland Environment Agency (NIEA) in Northern Ireland. So far thirteen lists are available (Publications – Red Lists, 2022). These lists don’t necessarily match with the IUCN Red List, which is based on Global Data, what might be critically endangered on a global scale may not be on a national scale and vice versa so using both as guidance for conservation actions would be ideal however for the scope of this report the actions recommended will be based on the IUCN Red List for Ireland. As per Figure 1, the search used was limited to Critical Endangered (CR), Endangered (EN), and Vulnerable (VU) species of Ireland resulting in 113, with a breakdown in the taxonomy of 21 from the Fungi Kingdom, 8 from the Plantae Kingdom and 84 from the Animalia Kingdom.

MAJOR THREATS TO WILD SPECIES IN IRELAND
To identify the major threats to wild species a table was created from the search of all the data for each threat listed and the Animalia Kingdom was categorised in more detail into Mammal, Bird, Amphibians, Fish, Reptile, Mollusc and Insect (Table 1).
Table 1: Analysis of Threats to Species on the Red List, Ireland.

From this information it is evident that there are a significant number of threats to several varied species but that groups of species and sections of threats could be extracted from it to focus on for consideration of conservation actions as one threat affected many species and many of the sub threats were affecting the same species.
For example, taking pollution, or agriculture & aquaculture with all the sub threats under those headings and addressing them would benefit species across the board. Reviewing the results from the search based on this information it was noted that the mammals were all sea mammals that would be impacted by actions decided on for sea fish except for the European Rabbit which is currently not endangered in Ireland though it is on mainland Europe and while they should be monitored there may be other areas to concentrate on that will have a higher impact. It was also noted that while Amphibians have no endangered listing on the Global IUCN Red List for Ireland the Natterjack Toad is listed as Endangered on the National List (King, Marnell, Kingston, 2022). Once conservation actions based on information from the IUCN Red List are established it may also be beneficial to examine the 13 Red lists completed nationally. It will also be beneficial when detailing actions to have the sub threats and to note which ones are the most significant and therefore more urgent, but the main information is easier to identify in the compacted Table 2 which has the larger numbers in red.
Table 2: Threats to Ireland’s Species on the IUCN RED List.

In Figure 2 we can see that some species are faring worse, birds (orange), fish (yellow) and fungi (brown), with five main threats standing out – Biological Resource Use, Pollution, Agriculture & Aquaculture (between Energy Production & Mining and Residential & Commercial Development on the chart), Residential & Commercial Development and Climate Change & Severe Weather. Concentrating on Biological Resource Use alone would have a huge impact, however given that Fungi live in so many different environments and are so essential in protecting plant biodiversity and soil health concentrating some actions towards them would impact many other species too and they are heavily impacted by the other main threats identified (Mommer, L., Cotton, T.,Raaijmakers, J.M., 2018).

Having identified five main threats a chart (Figure 3) and table (Table 3) were created
focusing only on those to further identify which impacts what the most.

Figure 3: Largest Threats to Ireland’s Species on the IUCN RED List. (Modified from
Source: The IUCN Red List of Threatened Species, 2022)
These show that fish are mostly affected by Biological Resource Use and Pollution, the threats to concentrate on for Fungi are Residential & Commercial Development,
Agriculture & Aquaculture, and Pollution, and looking at conservation actions in the areas of Biological Resource Use, Pollution, and Climate Change & Severe Weather would benefit the bird population most.
Table 3: Largest Threats to Ireland’s Species on the IUCN RED List.

NECESSARY CONSERVATION ACTION TO ALLEVIATE THREATS TO WILD
SPECIES IN IRELAND
Based on the above assessment of threats the most important areas on which to focus conservation actions for Ireland, are reducing the five threats in table 3 for the 3 species groups of Fish, Fungi, and Bird. It is assumed that the many other species also affected by these threats would also benefit from conservation actions taken based on the spread in Table 1. Reducing the search criteria to just include these main threats on an individual basis gave access to further stats on the IUCN Red List Search (Figure 4) which will assist in the analysis and actions needed process as it shows us the main focus points in each threat, the reference number are as per their references on the IUCN Threats listing:
- 5 – Biological Resource Use
Per Figure 4, page 11, there are four substantial threats under 5.4: Fishing and
Harvesting Aquatic resources as follows in order of severity.
o 5.4.4 Unintentional effects: (large scale) harvest
o 5.4.3 Unintentional effects: (subsistence/small scale) harvest
o 5.4.2 Intentional use: (large scale) harvest
o 5.4.1 Intentional use: (subsistence/small scale) harvest - 9 – Pollution
Per Figure 4, page 11, the two largest pollution threats are under 9.3 Agricultural and Forestry Effluents.
o 9.3.3 Herbicides and Pesticides (24)
o 9.3.1 Nutrient Loads (18) - 1 – Residential & Commercial Development
There are three subcategories on the IUCN Red List under this and all are relatively high. - 1.1 Housing and Urban Areas (31)
- o 1.2 Commercial and Industrial Areas (24)
- o 1.3 Tourism and Recreational Areas (17)
- 2 – Agriculture & Aquaculture
Per Figure 4, page 11, two threats are substantially larger than the others in this category.
o 2.1.3 Agro Industry Farming (22)
o 2.3.3 Agro Industry Grazing, Ranching or Farming (20) - 3 – Climate Change & Severe Weather
Per Figure 4, page 11, one threat stands out among the many climate change threats.
o 11.1 Habitat Shifting and Alteration (25)
Just by focusing on the results shown from Figure 4, page 11, as outlined above there are clear areas to focus on but with 113 listed species of vulnerable, endangered, and critically endangered just a few were assessed in more detail given that many face the same threats and the same conservation actions could be applied :
- Fish
o Biological Resource Use – There are intentional and unintentional threats during the harvest of fish inland and at sea, both at the commercial level and the subsistence level, however, there is a small hierarchy of threats with
unintentional threats over intentional and also with commercial over
subsistence so the initial focus should be on the practices and reducing the
unintentional threats.
Reading through some of the fish on the Red List lessons can be learned and actions that worked used for others. The Common Blue Skate is Critically Endangered Globally, and the population is still decreasing however there have been a number of fishery-independent trawl surveys since EU fisheries regulations listed it as a prohibited species which may be allowing population growth. Therefore, if all the fish that are Vulnerable, Endangered or Critically Endangered were listed as prohibited the “unintentional” harvest should in theory decrease as more care is taken (Ellis, McCully-Philipps, Sims, 2021).
Proposed Conservation Action: Regulation, listing species as prohibited.
Using the same example, it is a general practice among recreational anglers in the UK and Ireland to return live skates. Many also recording, tagging, and releasing their catches (Ellis, McCully-Philipps, Sims, 2021) .
Proposed Conservation Action: Educate and Inform Recreational Anglers and encourage their participation in the conservation process of recording and tagging.
Using another example from the Red List, the Freshwater Pearl Mussel shows how so many threats can be there at one time, it faces most of the threats outlined in Figure 4 and more besides. While it is an extreme example, the threats it faces affect the other listed fish and species and the conservation actions that could be taken for it will apply also. (Cordeiro, Seddon, Moorkens, 2017). Sediment accumulation in the riverbed seems to be the largest threat and that can occur from agricultural practices, residential and commercial development, pollution and climate change. It
reflects what is now becoming more and more apparent in Ireland, more than half of our waterways are not well. According to the Sustainable Water Network of Ireland (SWAN) there are a number of causes, which tie in with the threats to fish from the Red List and Industrial Agriculture is the most significant – fertilisers, slurry, drainage and the destruction of habitats. Residential and Commercial Development adds to that with dredging, drainage and waterside development and so on (SWAN, 2022).
Proposed Conservation Action: Increase the number of designated Special Areas of Conservation (SAC), Education and Awareness, Encourage reporting of pollution, Visible action and enforcement of laws already in place, incentivise more sustainable agriculture practices.
Fungi
o Most of the Fungi listed are listed as vulnerable but more study is needed. They also come from varied habitats, those near waterways are susceptible to many of the same threats as fish and much of the same conservation actions are required. The Felted Pinkgill is found in semi -natural grassland to subalpine areas of Europe and Russia and is a good example for a wider selection (Jordal, 2019). The intensification of industrialised agriculture practices, development projects, and pollution (airborne nitrogen deposition have impaired the habitat of this fungi and the population is decreasing (Jordal, 2019).
Proposed Conservation Action: Many of the actions proposed regarding the Pearl Mussel would apply and as suggested on the Red List site payment for conserving should be considered an option and site management is also key (Jordal, 2019).
Birds
o The European Turtledove was chosen as an Inland example because it is not obscure as some other examples may be and is antidotally spoken about with love and nostalgia so could be used as a mascot species perhaps. It is vulnerable and undergoing rapid decline due to similar threats mentioned in previous examples (Hermes, 2019). The change in agriculture practices has impacted this bird, and many more, mainly by the loss of habitat, hedgerows and areas of scrub being destroyed in the name of larger pasture and monocrop land. Spraying of herbicides have added to their decline. They have reduced food supplies and nesting grounds. Less hedgerows and trees in urban areas have also seen their decline there (Hermes, 2019).
Proposed Conservation Action: Many manageable actions have been outlined starting with further gathering of information, mapping migration routes, manage known habitats, educate and encourage farmers and others to maintain hedgerows and breeding grounds and scrubland for wildlife (Hermes, 2019).
A seabird that is much loved by all and very recognizable even more so perhaps than before due to a creature in the StarWars movies being inspired by it and an animation program, Puffin Rock, being built around its “cuteness” is unfortunately also meeting the criteria for being listed as Vulnerable, (Birdlife International, 2018). This bird is being threatened by some of the aforementioned threats but is in particular vulnerable to climate change; changes in sea temperature, loss of food, changes in hunting habits of marine and terrestrial predators, extreme weather all of which reduce breeding and increase mortality rates (Birdlife International, 2018). Humans are adding to the risks with overfishing of the prey of the Puffin, introduction of invasive species predators such as mink, windfarms, oil spillages. Deaths have been caused by other pollutants and garbage (Birdlife International, 2018).
Proposed Conservation Action: Increase the number of Special Protection Areas and monitor the buffer areas. In the recommendations one that is very achievable is developing codes of conduct for activities such as tourism. Developing regulations and laws, manage fishing and continued monitoring. (Birdlife International, 2018).

CONCLUSION
Based on the advanced search carried out on the IUCN Red List for Vulnerable, Endangered and Critically Endangered Species in Ireland 113 were listed in various
taxonomy, The search included all 12 categories of threats and all habitats to catch as many as possible. An analysis of species against the threats was performed to narrow the examination. Five major threats across the three species of Fish, Fungi and Bird were found and a short examination of these found many similar threats and impacts and possible conservation actions that could be recommended. In order to understand what actions could possibly be undertaken some sample species were looked at on the Red List of 113. It was noted that the Global Red List does not always match the national Red Lists and both should be reviewed when considering actions. The common thread of most of the threats was an underlying lack of consideration or understanding of nature in residential, commercial, agricultural and aquacultural practices. Humans are “Doing without Considering”. There also seems to be a lack of understanding of the links between the natural world and our own human world. Knowledge in biodiversity, ecology, permaculture, sustainable living, working and farming and a holistic view of the world would remedy many of the illnesses of this world and should be part of every decision making process. Many of the actions identified reflect a holistic approach and where they are not applied regulation, legislation and monitoring are needed. The IUCN Red List is not complete, in order to be more effective more research of species is required and if the general public, commercial bodies and agricultural entities are encouraged to take part in completing some of that work they will be more connected to the Barometer of Life and mindful of its fluctuations.
