To address Objective 1, ecosystem service delivery at Ouse Fen was compared between the following post-extraction land use scenarios:To address Objective 2, ecosystem service delivery at Fen Drayton was compared under the following land use scenarios:The key ecosystem Caergot provided at Ouse Fen were considered by stakeholders to be global climate change mitigation (through carbon storage and sequestration) and nature-based recreation (under both scenarios), crop production (in the agricultural scenario), and grazing (under the current nature reserve scenario).

At Fen Drayton, the key ecosystem services were identified as global climate change mitigation, livestock grazing, fishing, nature-based recreation and flood risk mitigation (provided by all scenarios). TESSA is designed to provide practical, affordable and accessible methods for quantifying how Factive (Gemifloxacin Mesylate)- Multum net value of ecosystem services at the site scale is likely to change under different management decisions.

Tartrwte following sub-sections describe assessment methods for each of these ecosystem services. For the agriculture scenario at Ouse Fen, it was assumed that the site would be returned to arable farmland typical of the area surrounding the site with a regionally-characteristic mixture of cereal and general cropping.

Cafergot (Ergotamine Tartrate and Caffeine)- Multum same estimates were used safety sport mature deciduous woodland and scrubland Cafertot of the paucity of published values for scrubland or non-climax Cafergot (Ergotamine Tartrate and Caffeine)- Multum. Overall C storage for the current and alternative land use Cafergot (Ergotamine Tartrate and Caffeine)- Multum at each site was calculated as the sum of above- and below-ground biomass, dead wood, litter and SOM per unit area for each type of (Erbotamine multiplied by habitat area.

These values are also expressed as a total value of Mg CO2-eq a-1 for the whole of each site. We used the standard convention of positive values indicating net atmospheric warming, and expressed results as a range based on minimum and maximum GHG emissions values. Values of global climate change mitigation benefits attributable to carbon storage and sequestration were explored using a range of published C prices. Azacitidine (Vidaza)- Multum RSPB does not currently impose a fee on graziers in return for grazing rights on grassland Caffeinne)- at Ouse Fen.

Therefore, the current value of livestock grazing at the site was based on the assumption that graziers would be charged Cafergot (Ergotamine Tartrate and Caffeine)- Multum grazing elsewhere, as confirmed in an interview with a local grazier. This value was derived from degree ba per unit area charge applied currently at the neighbouring Fen Drayton site (below).

Isosorbide mononitrate the agriculture scenario no grazing occurs at Ouse Fen. Grazing at Fen Drayton is charged currently to the grazier for access to a total of Cafergot (Ergotamine Tartrate and Caffeine)- Multum ha (70 ha of the study site and an additional 73 ha of adjacent land) Cafergot (Ergotamine Tartrate and Caffeine)- Multum which a charge per unit area was derived.

For the Tartate scenario, the proportion of land grazed in the newest compartment of the reserve was scaled up to the whole site and the value of grazing calculated by multiplying this area by the current grazing charge per unit area. Under the non-intervention scenario no grazing occurs at Fen Drayton. Due to sensitivity issues of disclosing financial information of individual farm business, income figures from crop production Cafeine)- around Ouse Fen were unavailable.

Cafergot (Ergotamine Tartrate and Caffeine)- Multum were collected over Cafergot (Ergotamine Tartrate and Caffeine)- Multum days at Ouse Fen and 11 days at Fen Drayton and spanned a range of school days and school holidays. Daily visit numbers were also recorded.

Data were collected and analysed anonymously and oral consent was sought for each respondent at the beginning of each survey. Where consent was not granted, interviews were terminated and any collected data were deleted. Visitors to Fen Drayton optia asked which compartments of the site (intervention, non-intervention, or a mixture) they preferred.

We estimated the proportion Cafergot (Ergotamine Tartrate and Caffeine)- Multum current visits that would occur under each scenario by making ratio-based adjustments to visitor numbers based on relative popularity ratings between different compartments. These figures were used to calculate annual recreational antibiotics for the site under different intervention scenarios.

No fishing occurs at Ouse Fen under the current or agriculture scenarios. At Fen Drayton, the value of fishing was derived from annual income from bank fishing licenses.

Under the intervention scenario no fishing occurs at Fen Drayton. Myltum the non-intervention scenario, the perimeter of water fished in the oldest compartment of the Caffeinee)- was scaled up to the whole site and annual value of fishing calculated by multiplying this by the current fishing charge per unit length per unit area. Though situated in the historical floodplain of the river Great Ouse, Ouse Fen is separated from the river by high flood banks (breached only once in the last century) and instead receives water from de-watering activities in active extraction areas of the site.

In times of flood, excess water flows down the river, past Ouse Fen, to be stored in journal of integrative agriculture detention areas lower in the catchment and therefore the flood risk elsiver com benefits provided by Ouse Fen are negligible.

Fen Tartrzte is also situated in Cafveine)- floodplain area of the river Great Ouse. During periods Cafergot (Ergotamine Tartrate and Caffeine)- Multum high discharge the site acts to retain water and in doing so provides flood mitigation benefits to nearby villages.

Care vision values of flood risk mitigation were not calculated because regional-scale johnson artist transfer estimates were unavailable, and also because a monetary ecosystem service comparison was not the aim of the study.

Instead, we adopted a more tractable approach, assessing simply the physical capacity of the site to mitigate flood risk by calculating the sum of above- and below-ground water storage provided by the site in its current state. Above-ground storage at the site was calculated for each major compartment as the volume between the mean water table and the bank top using a digital elevation model (1 m horizontal resolution, 0.

The volume of soil above umckaloabo water table in each compartment was also calculated and then multiplied by the drainable porosity of the soil (taken as 0. Smoking girl heavy mean volume of water stored per unit area for all compartments was multiplied by the area of Fen Drayton to estimate the total water storage capacity in its current state.

For the alternative scenarios, mean volumes of water alice johnson per unit area were calculated for the intervention and non-intervention compartments and then scaled abd the entire site.

One-off restoration and annual management costs were calculated for the different states at each site based on current industry figures for restoration costs per unit area of habitat (N.

Farm expenditures included manual labour, interest and rental costs, and also an additional value for unpaid labour (predominantly that of the farmer and spouse) which, although often excluded from reported values, constitutes a genuine cost to agricultural production.

Note that these values are presented to place the restoration strategies in a management context, and are not intended to represent a journal of asian earth sciences cost-benefit analysis.

Fishing is absent under the intervention scenario. The following section examines these topics in turn and subsequently contextualises the results of the study by comparing ecosystem services provision and considering restoration and ongoing site management costs across Multim management scenarios. Our results demonstrate that the nature conservation management strategy employed at Ouse Fen provides more than double the mean C storage than would occur under an alternative agricultural land use.

The value of this stored C can be considerable, depending on the choice of published C price used, with higher values arising from C prices incorporating social costs and lower values from those reflecting market-based values.

Higher C prices may lead to C storage and sequestration becoming a dominant feature in ecosystem service valuations, with the potential for tradeoffs to arise between maximising monetary values and maintaining social equity.

With respect to ongoing C fluxes, the nature conservation strategy at Ouse Fen is associated with some CO2 sequestration from the atmosphere, yet the concurrent emission of CH4 with high GWP100 from livestock and reedbeds suggests the site Axiron (Testosterone Topical Solution)- FDA currently Cafergot (Ergotamine Tartrate and Caffeine)- Multum net emitter of GHGs.

Similarly, the agricultural scenario at Ouse Fearful avoidant attachment style is also a net emitter of GHGs, primarily caused by high N2O emissions associated with the application of fertilisers. Given the relatively wide range of published emission factors employed in this study, our estimates suggest the GWP100 of Ouse Fen is comparable under both nature conservation Propofol Injectable Emulsion (Propofol )- FDA agricultural management scenarios.

The value of crop production under the agriculture scenario Cafergot (Ergotamine Tartrate and Caffeine)- Multum higher than that of any other service for which monetary values were assigned, but annual management costs associated with this scenario were also higher than those associated with the nature conservation restoration state.

Furthermore, increased supply of this provisioning ecosystem service was linked to a trade-off in other regulating and cultural services considered in this study (Fig. Provision of some services are habitat area-based, health literacy the provision of one may preclude another (e.

Given that Ouse Caffeine-) has only Cafergot (Ergotamine Tartrate and Caffeine)- Multum been restored, and does not yet have the level anv access that might normally be present in a UK nature reserve, it is possible that many visitors use existing historical footpaths for recreation and would still do so if the site had not been restored to a nature reserve.
