“…The sensitivity of the rate and location to inject water used two laboratory-scale sandboxes under hydraulic confinement to measure the wedge length reduction. The coastal aquifers are principal sources of freshwater in various parts of the world due to their groundwater quantity and quality, suitable to cover water needs of cities, rural villages and agricultural and industrial activities (Acosta & Donado, 2015;Carruthers et al, 2013) The seawater intrusion prediction with or without mangrove vegetation showed that mangrove ecosystem has an important role in reduction of seawater intrusion in Jakarta. The simulation model also explained the role and function of mangrove to prevent, release and reduce seawater intrusion (Soerianegara, 1987;Hilmi, 1998).…”

CORRELATION ANALYSIS BETWEEN SEAWATER INTRUSION AND MANGROVEGREENBELT. Seawater intrusion is an entry process of seawater to land. Many factors have caused seawater intrusion from freshwater exploitation until mangrove degradation. Mangrove ecosystem is a type of forest ecosystem which has an ability to reduce seawater intrusion. This paper analyzes the estimation and prediction of seawater intrusion and correlation between widths of mangrove with seawater intrusion. The relation analysis between the width of mangrove greenbelt with seawater intrusion used an equation model to predict seawater intrusion. The research method used sampling technique, system analysis with powersim software, correlation analysis and mathematical method with trend line analysis. Results show that (1) the mangrove density in the coastal area is approximately 50 -109 trees/ha. (2) Simulation results showed seawater intrusion rate was about 0.20 km year -1 (with mangrove as a component system), but reached 0.3 -0.4 km/year (without mangrove as a component system). (3) The simulation result also showed that freshwater salinity was estimated to increase from 1.92 ppt to 4.86 ppt. (4) The relation model between seawater intrusion and mangrove greenbelt showed that correlation coefficient was 0.97 with the equation seawater intrusion (m) = 2264.9 * exp (-0.009 * the width of mangrove greenbelt (m)), the correlation of mangrove width with seawater intrusion was 0.97. (5) Avicennia marina, Avicennia alba, Rhizophora styllosa, Sonneratia alba and Sonneratia caseolaris were the mangrove species that had the best ability to reduce seawater intrusion.Keywords: Seawater intrusion, mangrove, water salinity, system analysis ANALISIS KORELASI ANTARA INTRUSI AIR LAUT DENGAN JALUR HIJAU MANGROVE.

“…On the one hand monitoring and assessment undertaken to inform the conservation of socioecological landscapes must be holistic enough to capture not only nature conservation-related biological value, but also measures of other forms of value relating to social and cultural processes that co-produced the landscape, such as agricultural productivity, as well as metrics of landscape management in order to operationalise the responsive management approach and tighten the adaptive cycle (Uychiaoco, 2005;Carruthers et al, 2013). On the other hand, a broader range of evidence of past management should be considered, along with recognition that past practices will have been site context-specific and have varied in space and time.…”

“…Debates revolve around not only clarity of survey design, aims and objectives, but also the relevance of much biodiversity monitoring to management decision-making (Danielsen et al, 2005), as well as more fundamental questions of what kind of data should be collected and the utility of expert versus experiential data (Fazey et al, 2006). Some authors have noted the need to close and tighten the adaptive management cycle (Uychiaoco et al, 2005;Carruthers et al, 2013), although the impacts of management operations are not always well understood (Crofts and Jefferson, 1999;Freese et al, 2014).…”

“…Globally, many conservation stakeholders responsible for the management of nature protected areas commonly hold to a model of responsive or adaptive management as a valid approach for a wide range of systems, from coastal barrier islands (Carruthers et al, 2013) to fisheries (Uyachiaoco et al 2004) and European grasslands (Crofts and Jefferson, 1999;Robertson and Jefferson, 2000;Soane, 2012). This model relies on a cyclical process of monitoring and assessment to follow evolution of both system condition and management operations, in order to inform subsequent management decisions (Greenwood and Robinson, 2006).…”

Contemporary practice in the conservation of socio-ecological landscapes draws on both a model of responsive management, and also on ideas about historic management. This study considered what evidence might exist for the exercise of these approaches to management in the conservation of floodplain meadows in England, in order to inform understanding and knowledge of conservation management and assessment practice.Evidence for a model of responsive management was limited, with managing stakeholders often alternating between this model and an alternative approach, called here the 'traditional management approach', based on ideas, narratives and prescriptions of long-established land management practices. Limited monitoring and assessment appeared to undermine the former model, whilst uncertainty over past long-standing management practices undermined the latter. As a result of the relative power of conservation actors over farmers delivering site management, and their framings of meadows as 'natural' spaces, management tended to oscillate between aspects of these two approaches in a sometimes inconsistent manner.Conservation managers should consider the past motivating drivers and management practices that created the landscapes they wish to conserve, and bear in mind that these are necessarily implicated in aspects of the contemporary landscape value that they wish to maintain. They should ensure that assessment activity captures a broad range of indicators of site value and condition, not only biological composition, and also record data on site management operations in order to ensure management effectiveness. Highlights management models for socio-ecological landscapes can be inconsistently applied  assessments can be too partial to assist responsive management decision-making  normative ideas about the value of nature influence interpretation of evidence  conservation management tends toward a historical-contemporary hybrid

“…Factors that affect coastal vegetation recovery rates, including herbivory (Carruthers et al, 2013;Keiper, 1990;Seliskar, 2003) and trampling (Bowles & Maun, 1982;Santoro et al, 2012;Šilc, Caković, Küzmič, & Stešević, 2017), have the potential to also affect resilience to future storms (Houser et al, 2015;Vinent & Moore, 2015). In this manuscript, we define resilience as the system's ability to respond to disturbance without losing ecological function (Klein, Smit, Goosen, & Hulsbergen, 1998).…”

Coastal resilience is threatened as storm‐induced disturbances become more frequent and intense with anticipated changes in regional climate. After severe storms, rapid recovery of vegetation, especially that of dune‐stabilizing plants, is a fundamental property of coastal resilience. Herbivores may affect resilience by foraging and trampling in disturbed areas. Consequently, assessing the impacts of herbivores on recovering vegetation is important for coastal land management.We combined imagery classification, wildlife monitoring, and trend analysis to investigate effects of white‐tailed deer on recovery rates of vegetation four years poststorm in nine overwashed areas. We estimated local deer density with trail cameras, how it relates to an index of primary productivity, and assessed the relationship between deer density and rates of vegetation recovery in overwash fans.Prestorm vegetation cover consisted of shrubs and sporadic patches of beach grass. Poststorm cover was dominated by beach grass. At current rates, vegetation coverage will return to prestorm conditions within the decade, though community transition from grasses to shrubs will take much longer and will vary by site with dune formation.The effect of deer on rates of vegetation recovery was negative, but not statistically significant nor biologically compelling. Although effects of deer trampling on beach grass are evident in classified imagery, deer foraging on beach grass had little effect on its rate of spread throughout overwash fans.While the rate of spread of the primary dune‐building grass was not deleteriously affected by deer, locally high deer densities will likely affect the future establishment and development of herbs and shrubs, which are generally more palatable to deer than beach grass.
