“…Though, the steppingstone patches in the basin would increase the matrix permeability there are few suitable habitats. This is a recurrent scenario in México, where fragmentation has reduced the large areas and increased the number of small-area patches [3,4,7]. Therefore, particular efforts should be enacted to preserve these large area patches or increase the size of the small ones by restoring vegetation in the vicinity.…”

“…Overall, deforestation is caused by direct factors such as the expansion of agriculture and urban areas [5,6]. The change in vegetation cover results in a fragmented landscape composed of forest remnants with different sizes and shapes that still sustain some ecological processes and values [7][8][9][10]. In other words, during fragmentation the landscape is transformed from a continuum habitat to an ensemble of fragments immersed in a matrix that is different to that of the original vegetation [8,11,12].…”

Connectivity is a landscape property that promotes gene flow between organisms located in different patches of habitat and provides a way to reduce habitat loss by maintaining flux of organisms through the landscape; it is an important factor for conservation decisions. In this study, we evaluated the structural and functional connectivity among 510 oak forest remnants in a basin in central Mexico by modeling the potential distribution of seven oak species that inhabit in it. The structural and functional connectivity of oak forest remnants was estimated by graph theory. Distribution models for all the oak species had a good level of predictability, showing that 53.16% of the basin is suitable for oaks. The importance for connectivity varied between the remnant forests. Large forest fragments had the highest values of connectivity, and small forest fragments acted as steppingstones favoring the movement of organisms among fragments. In the southern region of the basin, connected remnant forests had conformed to a large network, but in the northern region, the remnant forests were mostly isolated. Conservation of oak forests in this basin requires protection for remaining patches by preserving both large and small ones and restoring biological corridors to reduce the isolation of forest fragments.

“…The remaining secondary forests are planned for sports and recreation, educational institution, utility, and commercial use. Land use cover change in secondary forests will increase the landscape's fragmentation level and accelerate the fragmentation process of ecosystems [35]. To maximize the conservation benefits of secondary forests, integrating local and regional patterns of fragmentation is critical [19].…”

With past and continued loss of secondary forests in urban areas, this paper aims to assess the current distribution of secondary forests and evaluate the ecological values of secondary forests in terms of patch sizes, plant density and biodiversity values by using the analysis tools of GIS and FRAGSTATS. According to the analysis in this paper, over 1782 ha of secondary forest cover in Singapore has been lost due to the urbanization, such as residential and infrastructure development, in the past decade. It is estimated that about 7331 ha of secondary forests are planned to be cleared for new development. The future loss of secondary forests is about 1.2 times larger than the entire area of all parks and nature reserves in Singapore. It is shown that secondary forests became more fragmented compared with 2011, and more than 80% of patches are smaller than 1 ha. Most of the secondary forests’ patches are with high plant density and high biodiversity values in terms of ecological connection. Discussions towards the improvement of biodiversity and phase development planning for secondary forests in a tropical high-density city are addressed in this paper. There is lots of potential to integrate secondary forests into future land use developments for improving biodiversity based on the literature review and analysis results.

“…Landscape indicators are common tools for reflecting the structural composition and spatial configuration of the landscape pattern [36,37], which has been used in previous studies extensively [38][39][40][41]. As forest landscape patterns are complex and cannot be measured using a single indicator, a set of landscape indicators is usually used to identify forest landscape patterns [42]. In order to characterize the landscape pattern of Chinese fir plantations in Jiangle County from 2010 to 2020, this paper, based on previous studies [38][39][40][41][42], by using Fragstats 4.2 software (Informer Technologies Inc., Gillette, WY, USA) to calculate the landscape index, selected Total Class Area (CA), Number of Patch (NP), Largest Patch Index (LPI), Edge Density (ED), Landscape Shape Index (LSI), and Aggregation Index (AI) (Table 1).…”

Since the early 1980s, in southern China, evergreen broad-leaved forests have been replaced by Chinese fir plantations on a large scale. By analyzing the dynamic change characteristics of the landscape pattern of Chinese fir plantations in the case study, the paper explored the current status and development trend of the landscape pattern of Chinese fir plantations after 40 years of manual intervention and natural succession. The paper, based on the three-period survey data on forest resources in 2010, 2015, and 2020, analyzed the dynamic changes of the landscape pattern of Chinese fir plantations from 2010 to 2020 and, by using a transition matrix and landscape index, simulated and predicted the landscape pattern of Chinese fir plantations in Jiangle County in 2025 by constructing a CA–Markov model with Jiangle County, Fujian Province, China, as the study area. The results showed that the landscape of Chinese fir plantations is the main component of the forest landscape in southern China, accounting for 12%. The landscape quality of Chinese fir plantations degraded, mainly shown in the facts that the Chinese fir plantations were juvenile from 2010 to 2020, and that the young and middle-aged forests became the main part of the landscape of Chinese fir plantations, accounting for 54.8%. The landscape area of Chinese fir plantations showed an increasing trend, which mainly came from other coniferous forests, other woodlands, non-woodlands and non-wood forests, and the replaced Chinese fir plantations were mainly eroded by bamboo forests. The evergreen broad-leaved forests, a kind of zonal vegetation, have been effectively protected in the past 10 years. In the future, the total area of Chinese fir plantations will continue to expand, and a small part of them will continue to be eroded by bamboo forests. In order to improve the landscape quality of Chinese fir plantations, it is necessary to adjust the age group structure of Chinese fir plantations, expand the proportion of mature forests, and, meanwhile, continue to protect evergreen broad-leaved forests and curb the expansion of bamboo forests.
