The Cerrado biome is an important tropical savanna that has historically experienced significant disturbance due to agricultural expansion, putting its biodiversity at risk.[1] Conservation efforts, such as the creation of protected areas, have been implemented in the past few decades in response to these disturbances. According to Brazil's National Registry of Conservation Units (Portuguese: Castrado Nacional de Unidades de Conservação), there are, as of November 2024, 560 protected areas within the Cerrado biome.[2] In Brazil, protected areas are known as conservation units, and those in the Cerrado account for 19% of all units in the country. In total, these conservation units make up roughly 17.96 Mha of land, which represents about 9% of the total area of the Cerrado.[2]
Biodiversity of the Cerrado
[edit]The Cerrado is exceptionally important in terms of biodiversity. Making up 21% of the country’s land area, the Cerrado is the second largest biome in Brazil after the Amazon.[3] Spanning 2 million km2, the region is characterized by woodlands, savannas, grasslands, and gallery and dry forests.[3] It is considered to be the most biodiverse savanna in the world and a global biodiversity hotspot.[4] Roughly 30% of Brazil’s biodiversity and 5% of the world's plants and animals exist in the Cerrado.[5][6] The region also has high levels of endemism, with 4,800 plant and vertebrate species existing only in this region.[1] 43% of Brazil’s surface water outside the Amazon can be found within the Cerrado biome, and half of Brazil’s major hydrological regions begin here.[5][1]
Deterioration of the Cerrado Biome
[edit]The creation of protected areas is considered to be one of the most effective tools in biodiversity protection.[6] Protected areas are essential for conservation in the Cerrado as the biome has been subject to intense deforestation and clearing in the past few decades. The main driver of this destruction is agricultural expansion, as soybean production and cattle ranching are major economic activities for Brazil.[3] Estimates indicate that over 50% of the original area of the Cerrado has been transformed into some form of agricultural use.[3] Roughly 46% of its native vegetation cover has been lost, with only 19.8% of this vegetation remaining undisturbed.[1] Devegetation continues to occur throughout the biome at an alarming rate, and projections indicate that if this continues, another 31-34% of the remaining biome will be cleared by 2050.[1]
History of Protected Areas
[edit]The first protected area in the Brazilian Cerrado was the Paraobepa National Forest which was established in 1950.[2] Until the early 1990’s, the progression of the network was slow, with only a handful of protected areas established each year.[2] During the late 1990’s and early 2000’s there was a boom of new protected areas, which coincides with the passing of Law No. 9.985, of July 18, 2000.[2][7] This law established the National System of Nature Conservation Units (SNUC) and defines the concepts for the creation and management of conservation units in Brazil, marking the beginning of their legal regulation.[7] Between 1997 and 2006, a total of 179 conservation units were established in the Cerrado, accounting for almost one third of the entire current network.[2] Since this boom, the rate at which new conservation units are created each year has slowed down but varies considerably from year to year.
Types of Protected Areas
[edit]Protected areas in Brazil are called conservation units (UC) and are governed by the National System of Nature Conservation Units (SNUC) . The SNUC itself is under the jurisdiction of the Ministry of Environment and Climate Change.
There are two groups of conservation units in Brazil, namely Integral Protection (IP) and Sustainable Protection (SP). Integral protection units exist to protect nature, and use of their resources is limited to recreation and tourism.[8] Sustainable protection units aim to reconcile the conservation of nature with the sustainable use of its natural resources.[8] Out of the 560 conservation units in the Cerrado, there are 176 integral protection units and 384 sustainable protection units.[2] Within each type of conservation unit, there exist several categories, which are each associated with a category of the IUCN protected area classification system.
All categories of conservation units can exist at the federal, state, or municipal level. Federal conservation units are managed by the Chico Mendes Institute for Biodiversity Conservation (ICMBio).[9] In the Cerrado biome, there are currently 241 federally managed conservation units, which make up 6.41 Mha of land.[2] State conservation units are managed by state environmental agencies.[9] There are currently 210 conservation units managed at the state level in the Cerrado, which make up 10.15 Mha of land.[2] Municipal conservation units are managed by the municipal environmental secretariats.[9] There are currently 109 conservation units managed at the municipal level in the Cerrado, spanning roughly 1.41 Mha of land.[2]
Integral Protection Units
[edit]IUCN Category Ia[10]
An area where scientific research and the preservation of nature are the main goals.[8] Visitation by the public is restricted to educational purposes.[8] As of 2024, there are 24 ecological stations in the Cerrado biome, covering 916.4 kha of land.[2] An example of an ecological station in the Cerrado is the Serra Geral do Tocantins Ecological Station, which is the largest in the biome.[2]
IUCN Category Ia[10]
The main goal of biological reserves is to preserve biodiversity.[8] The only interventions allowed are actions to recover ecosystems, restore balance and preserve biodiversity.[8] Visitation is allowed only for education purposes.[8] As of 2024, there are 6 biological reserves in the Cerrado, covering 8,196 ha of land.[2] An example is the Culuene Biological Reserve, which is the largest in the biome.[2]
IUCN Category II[10]
National Parks exist to preserve ecosystems that are ecologically significant and their beauty.[8] Visitation is less restricted, as recreational, educational, and environmental interpretation activities take place within National Parks.[8] Scientific research is also active within these areas. As of 2024, there are 116 National Parks in the Cerrado, covering 4.37 Mha of land.[2] An example is the Araguaia National Park, which is the oldest in the biome having been created in 1959.[2]
IUCN Category III[10]
Unique, rare and scenic natural sites are preserved here.[8] Visitors are allowed in natural monument areas, as long as the activity aligns with the objectives of the unit.[8] As of 2024, there are 18 Natural Monuments in the Cerrado, making up 46 kha of land.[2] An example of a Natural Monument is the Tocantins Fossil Trees Natural Monument, which is the largest in the biome.[2]
IUCN Category III[10]
Wildlife refuges protect natural environments to ensure the persistence and reproduction of species or communities of local flora and fauna.[8] Visitors are allowed for various activities.[8] As of 2024, there are 12 Wildlife Refuges in the Cerrado, making up 261 kha of land.[2] An example is the Corixão de Mata Azul Wildlife Refuge, which is the oldest in the biome having been created in 2001.[2]
Sustainable Protection Units
[edit]IUCN Category V[10]
APAs have particular natural, aesthetic, and cultural qualities that are important to the human population.[8] These areas are usually extensive and aim to protect biodiversity, manage the occupation of humans and promote the sustainable use of the area’s natural resources.[8] As of 2024, there are 114 Environmental Protection Areas in the Cerrado, making up 11.9 Mha of land.[2] An example is the Baixada Maranhense Environmental Protection Area, which is the largest in the biome.[2]
IUCN Category IV[10]
Generally consisting of a small area, these units aim to preserve regionally or locally important ecosystems that have unique characteristics.[8] These areas usually have little to no human occupation and can exist on public or private land.[8] As of 2024, there are 22 Areas of Relevant Ecological Interest in the Cerrado, making up 11.4 kha of land.[2] An example is the Cerrado Pé de Gigante Area of Relevant Ecological Interest.[2]
IUCN Category VI[10]
National Forests are areas with natural forest cover that consist mainly of native species.[8] The sustainable and multiple use of resources as well as scientific research are the primary goals of these units.[8] Traditional populations are permitted to retain their permanence in National Forests.[8] As of 2024, there are 11 National Forests in the Cerrado, making up 51.6 kha of land.[2] An example is the Cristópolis National Forest, which is the second largest in the biome.[2]
IUCN Category VI[10]
While publicly owned, traditional populations may occupy extractive reserves to support their lifestyle based on extractivism, subsistence farming and small animal husbandry.[8] These areas prioritize the sustainable use of their resources as well as the protection of the culture of these populations.[8] Scientific research can also occur here, and visitors are permitted.[8] As of 2024, there are 7 extractive reserves in the Cerrado, making up 100 kha of land.[2] An example is the Chapada Limpa Extractive Reserve.[2]
IUCN Category VI[10]
Similar to extractive reserves, traditional populations occupy these areas.[8] The sustainable systems of exploitation these populations have developed over generations are the main focus of sustainable development reserves.[8] Scientific research may also occur in these units, and visitors are permitted.[8] As of 2024, there are 2 sustainable development reserves in the Cerrado, making up 97.3 kha of land.[2] These are the Nascentes Geraizeiras and the Veredas do Acari Sustainable Development Reserves.[2]
IUCN Category IV[10]
These are privately-owned areas that aim to conserve biodiversity.[8] A number of activities are permitted in these units, namely scientific research, tourism, recreation and education.[8] As of 2024, there are 228 private natural heritage reserves in the Cerrado, making up 111.1 kha of land.[2] An example is the Buraco das Araras Private Natural Heritage Reserve.[2]
UNESCO World Heritage Sites
[edit]
Two conservation units in the Cerrado biome have been designated together as a UNESCO World Heritage Site: Chapada dos Veadeiros and Emas National Parks. Together they are known by UNESCO as the Cerrado Protected Areas, making up 38.14 kha of land.[11] These conservation units were inscribed by UNESCO in 2001 for two main reasons. Firstly, the units are centrally localized and have varying altitudes, making them robust areas of refuge for species.[11] Secondly, the units excellently represent the biodiversity of the Cerrado biome, with more than 60% of all plant species and almost 80% of all vertebrate species that exist in the region.[11] Many endangered species occur in these units, making them important targets for conservation.[11]
Both Chapada dos Veadeiros and Emas are National Parks that are federally managed.[2] As National Parks, they are registered as integral protection units and benefit from strict regulations preventing the direct use of their resources. Chapada dos Veadeiros National Park was established in 1961 and comprises 240 kha of land.[2] Its area overlaps with the Environmental Protection Area of Pouso Alto, which is a sustainable protection conservation unit that was established in 2001.[11][2] Emas National Park was established in 1961, and it makes up 132 kha of land.[2] Its management focuses on preventing the negative effects of the agricultural area that almost completely surrounds it.[11]
Effectiveness of Protected Areas
[edit]Concerns have been raised about the effectiveness of protected areas in the Cerrado given the small proportion of land they cover and their varying degrees of strictness. Overlapping conservation units is an area of particular interest given the redundancy of the same area being protected and the possibility of management conflicts.[12] In 2020, almost 40% of all conservation units in the Cerrado had some overlap with other units.[12] A total of 64 conservation units were completely within other units.[12] Most of these were areas of ecological interest within environmental protection areas, which are both sustainable protection units.[12]
When they are created, each conservation unit in Brazil should be assigned a management plan which outlines the conservation practices that will take place within the unit as well as a management council to guide its conservation.[13] The management plan establishes a number of guidelines and rules necessary for the management of the conservation unit.[13] This includes the zoning of the area, in which the conservation unit is divided into different sections categorized by their required degrees of protection.[13] The management council is responsible for monitoring the implementation of the management plan and acts as a link between local populations and stakeholders with economic or environmental priorities.[13] As of 2024, almost 40% of all conservation units registered in the Cerrado do not have a management plan and about 60% do not have a management council.[2]
Some studies have evaluated the effectiveness of protected areas in the Cerrado depending on their strictness. Sustainable protection units, which are less strict as biodiversity conservation is not their primary goal, have been found to be ineffective against deforestation.[6] In 2015, 85% of all protected areas in the Cerrado, excluding private natural heritage reserves, were environmental protected areas, which are sustainable protection units.[6] Integral protection units in the Cerrado are the most efficient in biodiversity protection in terms of reducing deforestation and maintaining species richness.[6][14]
Conservation units should be representative of the biome they protect.[15] In 2015, only two thirds of protected areas corresponded to remaining native vegetation in the Cerrado, with the other one third representing deforested areas within different conservation units.[6] Despite this, protected areas have been found to be effective in representing both ecosystem services and biodiversity of the Cerrado.[15]
Privately Owned Land
[edit]Privately owned land is essential for conservation efforts as the majority of remaining native vegetation in the Cerrado occurs in private properties and farms. In 2019, private lands held 57.9% of the remaining native vegetation in the Cerrado.[16] Brazil’s Forest Code requires land owners to retain 20% of native vegetation as Legal Reserves on their properties in all biomes except the Amazon, where the number is 80%.[17] Legal Reserves in the Cerrado are essential for biodiversity protection, as about 13% of the distribution range of threatened species exist within them.[18] Changes made to the Forest Code in 2012 legally allow almost 40 Mha of extra native vegetation to be cleared on top of the original allowance.[17] In 2017, this amounted to 40% of remaining native vegetation in the biome legally able to be converted.[1]
Compliance with the Forest Code by landowners is an issue in the Cerrado as some consider the legislation to be a roadblock for agricultural development.[17][19] There are measures in place to increase compliance, such as the Rural Environmental Registry System (CAR), which is a documentation system of environmental information of millions of rural properties that facilitates their monitoring and management.[17] Monetary incentives are also offered by the Brazilian government in the form of the Low-Carbon Agriculture (ABC) program to promote sustainable agriculture and forest restoration.[17]
Indigenous Land
[edit]Indigenous lands (IL) remain an important sector for biodiversity conservation in the Cerrado. The government of Brazil has recognized 4.8% of the Cerrado’s area as IL.[15] In 2019, 6.72% of remaining native vegetation occurred within IL, compared to the 2.27% that was preserved within conservation units.[16] Indigenous lands also effectively represent the ecosystem services and biodiversity characteristic of the Cerrado biome and are efficient in reducing habitat conversion and deforestation.[15][20]
