#6 UK Species & Habitats: Wetlands (Part 1)

ABOUT THIS EPISODE

Hello and welcome back to NatureLab! Today's episode will be the first half of a two-part podcast! Dan and Max will be discussing the conservation value of UK wetlands in the first half. This episode will look at the importance of UK wetlands to ecosystems and cover why and how they are protected. We will also cover some of the future threats to wetlands and how our generation hopes to combat these threats!    

Welcome back to Nag love the show herewe talk about everything and anything about nature. I'm your Co Host Max andDay Im joined this time, but just one co host Dan, the guys. So today it's going to be a little bitshorter than usual, but do not worry that there will be a second part today,we're going to talk about the UK wetlands and how that protected. Yes,Max is going to ask me some questions and what we now want to know about theconservation, status and threats and then we'll go over some consummationstrategies as well yep as like a plan. Okay, so Dan I've got a question foryou: Why are wet lands so important to the UK? Okay, well, first of ll justdefine what wetlands just clarify for everyone listening and then go into theecology there as well. Yes, sounds good, so wetlands areas, Marsh Fan, peatlandsor water and they can be natural or artificial and they can be static orflowing, and they can they can be in fresh brackish salt or even marine aswell, whether depth that low tired doesn't exceed six meters. This isreally broad, so if we look at the...

CLASSICA, it helps a little so the pogsfends peatlands, and then each of these are subdivided as well. Soclassification is down to the hydrology processes right, but what about the ecology of it?Okay, yeah! So so this actually an as your first question as well. Wetlandshave a number of services for the environment of society. A lot ofconservation is driven driven from the Carven Orage, which has increased withcarbon omissions. Although changes in climate can make wetlands either sinksor sources, so wetlands have also also have ground water interactions as well.So what Lens off of flood protection by mitigating the water level, althoughthe decline has reduced their value as a natural foot barrier in the north ofthe UK, wetlands provide feeding, opportunity for wildfire and a breedingenvironment of a waders as well. So the Millennium Micoe assessment in twothousand and five high lighted number of services or variable depend onclimate topography and the soil type as well wow. So wetlands do sound, reallyvaluable to us in the UK, but what...

...about their distribution like? Whatstate of the another minute they've been in the clime for a longtime, so currently they're being managed slightly better by the rams orconvention, which is an international treaty for protection. However, onlyten percent of original wetlands are left in the UK. Agriculture has been inone of the main drivers of the decline not just from the expansion, but alsofrom pollution. So methods like Pea, cutting water abstraction cause Wetmanto continue declining as well, so they owned a lot of pressure. You said therewas around only ten percent left. Does this mean that wet and distribution islimited? Well, yeah, because of the decline currently constructed. Wetlandsare distributed around the Midlands. This unsurrounded genever as well.Lowland reese bogs, the dominant type, although they're scattered acrossnorther, island, England, Scotland and then Lowland Fen mainly occurs in Wales,England and nothern. Ireland studies are also focused on the stanger for aculture impacts on the original wetlands left as well.

So early you mentioned some threats,but just for everyone listening. What are the main threats to wetlands? Well part from the obvious. We need toprotect a that. We have left so there are a lot of. There are a lot number ofthreats mentioned agriculture, expansion, which has been a huge threat,also pollution which might confuse some people, because wetlands can be used tomitigate pollution, but service run off carrying pesticate apsides and help ofbacteria can alter the conditions, making them less suitable for species.The national cives in two thousand and sixteen reported an inappropriate sitemanagement has also been classed as a threat, because a cultural machinerygrazing still being used methods like burning, were also using box to open upthe structure of the environment whatever that means, although this isan advice. Currently, I also mentioned Dran inch as well,which was used to make agricultural space and then hunts climate change fit sorry. Now, however, drainage is usedmore in constructed wetlands to manator water level, then there's a big one as well: ClimateChange, with Othmans, wetlands being so...

...specialized, local temperatures,increase of pretty large facts and the conditions essentially weak in wetlandscommon sources ron and things. This also increases of operation rates,altering a water table which could on at species of relying on the conditions,so climate change, orses, preception, an intensity again altering warderlevel and water log habitats can contribute to the COT emissions. Allthese threats highlight in need of conservation, but, like me- and youcould argue, everything needs protecting realistic. We are, we haveto pick up bottles, I think the level of degradation and the importance ofwetlands as services at definitely offers validation for that conservation.Yeah. Definitely. But if this was one of them like, if there is anyconservation, be done for the wet lands or and if there is, if there is, how isit done? What management and WANAGAN techniques how we're using? Well, it'spretty side dependent. There are organizations that push of conservation,both wet lands, are likely to have been...

...designated as some of the protectedhabitats. So I ever whatland Habitat Na where I live back home and it's societyspecial scientific interest, O triples, but it's surrounded by hunting ground.So that's not really ideal. I mentioned the Ramsai Convention earlier as well what they are also guides and documentsproduced that offer a visual management. These are more in direct type ofmanagement, though so there are some things in place, but I thinkconservation that makes makes the most impact is on side management in general.This is restoration and rehabilitation techniques, and this is where it comesside upon it. Dependent some sites may require a vegetation agreeable to whichis waterman. Another site may recue may require increase water levels. Then thespecies love management as well that takes place a grazing, the use tomaintain diversity, since it prevents succession and competition and thisallow species to flourish. Conservation also evolves monitoring in assessments,so the environment or impact assessments can be used to identifyissues and determine potential threat.

So, like climate change, I willidentify any aspects that might be vulnerable study also highlighted thenee spacial analysis when a sestet when assessing wetlands. This will determinethe sensual stretch such as flooding. Then you are monitoring as well. Thisis used in the UK to keep an eye on the hydrology and Hydrogeologie of thehabit. Art- and this has been encouraged by the runs or conventionthey're- also frameworks developed for project managers of monitoring methods.Also, population monitoring provides an opportunity to identify, indicatedspecies water quality which can on be implemented in to the side assessmentsas modeling as well. Where you can take past in present data, then you can useit projeck. The future in the site, modeling, would provide expectedresults which can have be contrasted to your current results as well. Sowetlands are can serve through different types of legislation as well,so the RAMSA convention came about in one thousand nine hundred and seventyone- and this is just one example- there are others, because wetlands areso diversely fall under so many...

...different categories, so trustallenvironmental laws, biological diversity, laws and the watermanagement legislation as well. Okay, so there is conservation for thepresent, but what about the future? What challenges do you front wetlandsface later on? Okay? Well, that's definitely, climate change, sotemperatures increase c level wise for coastal wetlands and then precipitationchanges as well. Temperature increase rates, the most concern in peat box,for example, so increased temperature micas further degredation from loveringthe water sable, and it cause a metabolic processes of decomposerspotential increases. Sorry at the Metaphor, process is a decomposespotentially making, but lens of common source. Increased climate intensity isalso expected, so models of Surin, the reduction in some of rainfall and theincreased evaporation or stress plan communities during the later summer, aarly autumn, especially in the south and the east of the UK Ye. The mainfuture challenge is population growth, as this incorporates a lot of otherthreats. Population increases usual correlated to a decrease in availableland, which means more people to feed,...

...and so our culture industries and morepressure than the Greece context. A conflict with nature for the availablespace organization in terms of land as well, has increased by around threehundred thousand hectares in one thousand. Nine hundred and ninety eightcording to defer en two thousand and six not only reducing and available,but also increasing the reason system, and this results have increased it toyou. It two emissions as well, creating and negative you but feedback loop toclimate change, but is there anything that can be done to a manager orprevent these up on coming for us and if in in planning at least well, there's, usually generalmanagement plans? So the rams are convention able to provide advice forfuture management and there has been more efforts to acquire land andconsulate with the intention of conservation. Although it's emphasizedthis is for multifurieuse agriculture as well. So multiple ituna on use isone of the ways that these challenges is going to be dealt with, but thismight require a trade off, although this is more feasible because it'scompromise the lightly implemented sooner. The National Environment Agencyis actually working towards this,...

...aiming to skil benefits for both peopleand the environment. Another concept as well as constructed wetlands, these maynot conserve the remaining right ones, rather provide an alternative. They alive from manipulation andthere's less reliance on the climate. So, as you found the still more tomanagements, be cost effective and when managing properly can provide possentiby diversity, there also recommendations for the future. So theWeland vision for England attempts to define POTENTIAL AREAS FOR FUTURE WETthe management restoration setting our fifty year. O agricultural changes arealso recommended to such as trout, resistant crop varieties and provewater storage and avoids using mechanic cultivation on water, og soils, but thesurprise convincing London is to change. So what you're saying is that there ishope, but it doesn't sound, very easy, yeah yeah there. It's not it's hard,not to be doing with conversation, especially concerning what lands fromhow much it's been reduced, but yeah. This there's definitely hope that'sgood.Well, I think we'll have to wrap it up...

...here. I don't buy anyone else, but Idefinitely understand more about wetlands now and how important theyactually are. But thanks for that, and if anyone wants to learn more aboutwell Lens, you can go to the website s dance mentioned or if you want to getgame volvers and these episodes or if you just want to ask any questionsabout the episode, make sure you've fallen at Nachel on Twite, that's anature under school lab and at Nate podcast in Instar, but that, as fortoday, nature Lub Sidin. Now.
