Using hydrologic suitability for native Everglades slough vegetation to assess Everglades restoration scenarios Using hydrologic suitability for native Everglades slough vegetation to assess Everglades. Categories Categories Connect with us on Twitter. We propose that hydrologic suitability of white water lily, Nymphaea odorata, an indicator species of the native Florida Everglades slough vegetation community, be used to evaluate modeled restoration scenarios in the Everglades ridge and slough landscape. Our analysis indicates that additional restoration efforts are needed to fully restore native slough vegetation communities throughout the Everglades ridge and slough landscape. There are numerous challenges associated with the unique hydrology of south Florida and the complexity of combining hydrology and operations in a single simulation model. Coherent picture of the pre-drainage Everglades emerges from extensive mapping of all available observations, combined with mechanistic understanding of processes of drainage-induced change. Journal Ecological Indicators — Elsevier Published: Jan 1, 2013.
Our case study provides a methodology for how to utilize hydrologic suitability for native vegetation to evaluate effects of modeled restoration scenarios. There is a tendency for many to consider the 1943 vegetation survey by J. It is a vast, fresh-water lake, of shallow depth, from 60 to 90 miles in length, and from 25 to 50 miles in width. Marshall Loxahatchee National Wildlife Re fuge, and consists of four 8 ha macrocosms Aich et al. Based on experimentally derived mesocosm and field studies and historical evidence, we developed a predictive performance measure to assess hydrologic suitability for N. Part 2 How do we know so much? The video disk contains historical observations and appendices. Rainfall and evapotranspiration are close in magnitude in south Florida and any changes in these components of the water budget may greatly impact water resource planning, management and restoration efforts.

Based on experimentally derived mesocosm and field studies and historical evidence, we developed a predictive performance measure to assess hydrologic suitability for N. In this instance, the cost of extra pages and higherquality printing apparently won out, and the reader is the unfortunate loser. Balancing the goal of the restoration with the stakeholder needs is where the research and information contained in Landscapes and Hydrology of the Predrainage Everglades will prove to be very valuable. The use of the historical township surveys provides a convenient tool for comparing areas between current and historical times, and it is quite remarkable how some fragments of the landscape have persisted through the decades. During the last 100 years, the system has been fragmented by human activities including drainage, channelization and physical changes to the system to allow rapid agricultural and urban growth.
Development of next generation models are underway to support the implementation of restoration projects and provide information for the engineering design and permitting of project features. We applied the performance measure to predict the hydrologic suitability for slough vegetation in the Everglades ridge and slough landscape using model-simulated hydrology of existing conditions, future conditions with restoration, and the predrainage Everglades. In contrast, by 2000, just over a century later, this same region had been so greatly altered by major anthropogenic disturbances that a massive restoration effort was initiated U. For the ecological restoration practitioner, it provides the basic information needed to develop a purposeful rephotography project and strongly suggests that repeat photography can be used to quantitatively and qualitatively assess changes in vegetation. We had staff in Daytona Beach for the Florida Native Plant Society conference, Orlando for the Florida Historical Society meeting, and Jupiter for the Florida Anthropological Society meeting. In reviewing works as old as 200 yr, the authors did a commendable job in reviewing the historical record to create an objective and consistent model of the predrainage Everglades landscape.
Chapter 3 lays the necessary groundwork for the reconstruction of the Everglades landscape presented in Chapter 4. When we speak of Everglades restoration, we are really talking about restoration of ecological function throughout the remaining system. The hypotheses suggesting fairly rapid and substantial changes to soil and vegetation put forward in this chapter are well supported with both scientific evidence and a wealth of firsthand descriptions of the landscape. The predisturbance Everglades of the 1800s was one of the last American frontiers. Abstract: In this chapter, we briefly discuss the development of the Everglades over the past 5 million years, the modifications made to the Everglades over the past century and a half and the quantification of the changes that have occurred to the peat soils of the Everglades due to natural and anthropogenic causes during this most recent period.
Simulation models have been used extensively to determine the performance of restoration alternatives and for planning operations of the existing system. Water grasses of several feet in height above the water cover its entire surface, except in a few channels or where there are small ponds of water with sand bottom from 3 to 5 feet deep. In fact, Davis and colleagues 1994 refers to the 1943 vegetation map as representative of the predrainage landscape. Our results indicate that Everglades restoration will provide the greatest benefits to native slough vegetation in Arthur R. Each of the four macrocosm contains two constructed tree islands that were each planted with 717 native trees between 2006 and 2007. Based on experimentally derived mesocosm and field studies and historical evidence, we developed a predictive performance measure to assess hydrologic suitability for N. Landscapes and hydrology of the predrainage Everglades.
Retrieved Mar 12 2019 from 9780813035352 Landscapes and hydrology of the predrainage Everglades. On a more positive note, I do believe that this book, despite its largely flawed visual presentation, represents the best overview of repeat photography available today. We applied the performance measure to predict the hydrologic suitability for slough vegetation in the Everglades ridge and slough landscape using model-simulated hydrology of existing conditions, future conditions with restoration, and the predrainage Everglades. Landscapes and Hydrology of the Predrainage Everglades review Landscapes and Hydrology of the Predrainage Everglades review Kotun, Kevin. We propose that hydrologic suitability of white water lily, Nymphaea odorata , an indicator species of the native Florida Everglades slough vegetation community, be used to evaluate modeled restoration scenarios in the Everglades ridge and slough landscape. Everglades is a rainfall-driven system characterized by seasonal, inter-annual, and inter-decadal variability in climate.
The system has changed so dramatically since the mid-19th century that restoration, in the true sense of the word, is simply not feasible. Soil Subsidence, 1910-1940 Mapping and Synthesis Drainage History. Davis as representative of the pre-drainage Everglades.

Those firsthand descriptions provide valuable insight into the conditions that existed prior to the construction of the first canals. It is interspersed with thousands of islands, from a quarter of an acre to several acres in area and generally having a few trees on them.
