\"032-035_Restaura\u00e7\u00e3o<\/a>The initial results from an ecological restoration project at Marupiara Farm in the municipality of Paragominas, in the Brazilian state of Par\u00e1, are beginning to appear, four years after the degraded areas there were isolated and the first seedlings of native species such as a\u00e7a\u00ed and andiroba were planted. The use of techniques such as artificial enrichment of forests, which adds new species to the growing vegetation, has led to the recovery of about 60% of the area partially destroyed by timber harvesting in recent decades. The property, which is used for cattle farming, had 17 hectares that were not in compliance with the law in 2011. These lands were supposed to function as Permanent Preservation Areas (APPs) to protect the rivers, the soil and the local biodiversity. The recovery program has also helped diversify the farm\u2019s output, as evidenced by the fact that a\u00e7a\u00ed and wood will soon be brought to market.<\/p>\n

The number of cases of this type could potentially increase over the next few years.\u00a0 In 2014, Brazil\u2019s federal government enacted the implementing regulations for the Rural Environmental Cadastre (CAR), an instrument created to regulate and monitor some 5.6 million rural properties. Completion of the cadastre in 2016 will initiate the Environmental Regulation Program, which will require rural landowners to restore areas that were illegally deforested in the past. \u201cThis will likely increase the demand for projects to restore natural formations in Brazil,\u201d says biologist Ricardo Ribeiro Rodrigues, a professor at the Luiz de Queiroz College of Agriculture, University of S\u00e3o Paulo (ESALQ-USP).<\/p>\n

Paragominas, one of the principal livestock centers in the Amazon Region, was at the top of the Ministry of the Environment\u2019s deforestation blacklist from 2008 to 2010. With pressure from the Office of the Prosecutor for the Public Interest, the city was able to get off the list with support from The Nature Conservancy, a U.S. nongovernmental organization, which helped register 80% of the properties in the rural environmental cadastre of the state of Par\u00e1. Once it was removed from the list, the city faced a new dilemma: how to keep from getting back onto the list of worst deforesters. \u201cThere was only one answer: we should adopt modern techniques that can transform livestock-raising in the region,\u201d says Mauro Lucio Costa, owner of Marupiara Farm and former president of the Rural Producers Union of Paragominas.<\/p>\n

The union requested help from researchers at ESALQ-USP, who have a wealth of experience in forest restoration studies. \u201cOur research findings come from studies done under the Biota-FAPESP program,\u201d says Ricardo Ribeiro Rodrigues, referring to the initiative begun in 1999 to map the biodiversity of the state of S\u00e3o Paulo. Rodrigues was coordinator of the program from 2004 to 2009. One result was a 2008 document that presents guidelines for conservation and restoration of the biodiversity in the state of S\u00e3o Paulo, based on the knowledge generated by Biota-FAPESP. The document recommends, for instance, that the remaining fragments of vegetation be taken into consideration in recovery projects, with an emphasis on riparian forests\u2014the vegetation growing along the edges of headwaters, rivers, streams, lakes and dams that protects the water from silting up, mainly through erosion, and also acts as a center for seed dispersal and creates ecological corridors.<\/p>\n

\"Intensive

There was one more challenge: convincing the farmers in Paragominas who are averse to change. \u201cMost of them only became engaged when they saw that the restoration projects were viable and could diversify production and generate a profit,\u201d Costa says. On Marupiara Farm, 12 native species were planted in legal reserve areas, where sustainable management is permitted for economic use. These species included ip\u00ea, Brazilian walnut, Brazilian cherry and medicinal plants, as well as timber trees such as andiroba. Work was also done to improve the pasture areas, which accommodate 2,000 head of cattle. Pastures on the flatter, more fertile land were improved and thickened. This made it possible to keep more cattle in a smaller space. In 2003, the property had 0.9 head of cattle per hectare; in 2015 that number rose to 3 head per hectare.<\/p>\n

Ricardo Rodrigues how heads a project to restore riparian forests, native forests for economic production and degraded forest fragments. The goal is to simulate and understand the effects of implementing the new Forest Code. The study seeks, for example, to identify the potential for using and marketing wood and non-wood products from native species and to develop low-cost methods of restoration. In addition to the academic studies, research groups such as the one at ESALQ are also endeavoring to test practical applications for a number of available techniques. Some of these efforts in Brazil are described in the book Restaura\u00e7\u00e3o florestal <\/em>(Forest Restoration), which was authored by Rodrigues along with Sergius Gandolfi and Pedro Brancalion, also professors at ESALQ-USP. The sixth edition of the book was introduced at the Ecological Restoration Symposium held November 9-13, 2015 in S\u00e3o Paulo.<\/p>\n

The book updates the theoretical framework drawn up in 2010 to provide technical support for the Atlantic Forest Restoration Pact, an effort that brings together 350 public and private institutions, companies, government agencies and landowners. The goal is to restore 15 million hectares of Atlantic forest by 2050. \u201cMany initiatives have had no guarantee of success, because the projects have been implemented incorrectly,\u201d says Rodrigues.<\/p>\n

Forest recovery on farms in rural S\u00e3o Paulo State is one of the initiatives carried out under the Pact. In 2012, three farms in Itu were chosen as sites for restoration activities intended to provide environmental compensation. The initiative works as follows: the owner of a sugarcane plantation that does not have areas suitable for forest recovery in a legal reserve can, for example, invest in remaining natural areas located on another property. \u201cWe\u2019re also putting 10,000-square-meter land parcels up for sale on some of the farms. Half the area is restored native vegetation. The objective is to form a forest corridor amidst the buildings,\u201d says business owner and sociologist Neca Setubal, who owns two farms in the area.<\/p>\n

The current Forest Code permits controlled exploitation of APPs on small properties, provided that species from the local region are used. In areas where sustainable management is permitted, the law authorizes the planting of up to 50% exotic species, such as eucalyptus, among native vegetation. In the state of S\u00e3o Paulo, the first resolution published by the state environmental department named 247 tree species to be used in restoration projects. The Botanical Institute, which is in charge of the listing, recently announced a revised and expanded list of 2,315 species that includes not only trees, but also tree ferns, shrubs, lianas, herbs, and other vegetation types. \u201cThe forest is not just trees. Successful restoration depends on the biodiversity involved and the genetic variability,\u201d says Luiz Mauro Barbosa, director of the Institute. In 2001, most of the recovery areas used no more than 30 species, nearly always the same ones. And nurseries concentrated on producing just a few types of trees. Now, the state has 207 nurseries that produce about 40 million seedlings of 800 arboreal species each year.<\/p>\n

The expanded list of species will be a strategic cornerstone of the Headwaters Program, a river conservation initiative based on forest restoration launched by the S\u00e3o Paulo State government in 2015. The objective is to protect 6,000 kilometers of streams and restore some 20,000 hectares of riparian forest. There have been three plantings, in the cities of Joan\u00f3polis, Piracaia and Jacare\u00ed, using more than 270,000 seedlings. The Green Initiative, a nongovernmental organization that will take part in projects under the state program, is one of the entities already at work in the area around the water system that supplies the city of S\u00e3o Paulo and other cities. The organization is participating through the Water Production Program run by the National Water Agency (ANA), in response to a call for proposals under the BNDES Atlantic Forest Initiative. \u201cIn three years, we were able to determine that planting seedlings improved the water quality,\u201d says Pedro Barral de S\u00e1, who heads forest projects for the Green Initiative.<\/p>\n

For the past three years, the municipality of Machadinho, in the state of Rio Grande do Sul, has been conducting a program to improve water quality and increase production by protecting headwaters. The initiative is devoted in part to associating the production of yerba mate with forests around the headwaters of rivers and streams. Several stakeholders are involved in the project, including the municipal government and the Brazilian Agricultural Research Corporation\u2019s forestry division (Embrapa Florestas). \u201cOver 50 properties are involved. We\u2019ve now recovered a number of headwaters, and the case has become a model for headwaters protection and ecological restoration. It even includes training for technicians,\u201d says Emiliano Santarosa, an analyst at Embrapa Florestas who is in charge of technology transfer operations in the region.<\/p>\n

Another recovery method implemented by Embrapa is the agrosilvopastoral system, which combines agriculture, livestock- raising and forests, and can increase productivity in the field without the need to expand the agricultural area into virgin forest. Embrapa is developing projects of this type primarily with dairy or beef cattle \u00a0farmers, who plant trees in pastureland. Partial shade offers comfort to the animals and, when properly planned, results in higher milk productivity, for example. In Paran\u00e1 State, there are over 40 properties that serve as models for the use of this system in projects carried out by Embrapa in partnership with the Paran\u00e1 Institute for Technical Assistance and Rural Extension.<\/p>\n

In S\u00e3o Paulo, experiments that combine sugarcane planting with native forest preservation are revealing a way for bioenergy production and forests to coexist in the same space. A 2012 study by Brazilian and American researchers showed that native forest can store 18 times more carbon than can sugarcane. And in a more recent survey, researchers at USP, along with colleagues at the National Institute for Space Research (INPE), showed that the state of S\u00e3o Paulo has a deficit of 800,000 hectares of forest that should be recovered. \u201cOne solution is to plant the sugarcane around forests, or vice-versa,\u201d suggests Marcos Buckeridge, a co-author of that study and coordinator of the National Institute of Science and Technology of Bioethanol (INCT-Bio). \u201cIn forest restoration, the difficulties lie in making the experiments work on a larger scale,\u201d he notes.<\/p>\n

Ricardo Rodrigues, the ESALQ-USP biologist, agrees with that assessment. \u201cThe projects implemented in Brazil are so far rather localized,\u201d he points out.\u00a0 Expanding the initiatives, says Rodrigues, depends on strategies to lower the cost of forest restoration projects and facilitate economic gains. In Itu, for example, the forest renewal on the three farms cost about R$20,000 per hectare. Because of the high degree of degradation, they had to plant a full complement of seeds or seedlings. \u201cThese are expensive projects, and the costs need to be brought down through the use of scientific know-how,\u201d Rodrigues says.<\/p>\n
