<p><strong>Background:</strong> Forest plantations with fast-growing native species contribute to the capture and storage of Carbon (C). However, little is known about the survival, the potential of capture and storage of C in plantations with native species of the mountain cloud forest in Mexico.</p><p><strong>Questions</strong>: Is the survival different between individuals of <em>Alnus acuminata</em> and <em>Trema micrantha</em> sown in experimental plantations? Are the annual carbon capture rate and the total C content between the two species different?</p><p><strong>Species of study</strong>: <em>A. acuminata</em> and <em>T. micrantha</em>, species of rapid growth of the mountain cloud forest (MCF). Both of early successional states.<strong></strong></p><p><strong>Study site and years of study</strong>: Central area of the state of Veracruz. 2009-2012.<strong></strong></p><p><strong>Method</strong>: In the experimental plantations of <em>A. acuminata</em> and <em>T. micrantha</em> of three and a half years of age, survival, diameter and height were recorded. With these variables, the volume, the basal area, the weight of the aerial biomass, the carbon content of the trees and height, diameter and carbon growth rate were estimated.</p><p><strong>Results:</strong> The survival of <em>A. acuminata</em> plants was greater than <em>T. micrantha</em> (P &lt; 0.05). The plantations of <em>A. acuminata</em> stored significantly more C (12.55 ± 0.05 Mg C ha<sup>-1</sup>) than the plantations of <em>T. micrantha</em> (11.62 ± 0.042 Mg C ha<sup>-1</sup>) (<em>P</em> &lt; 0.001). The annual rate of carbon capture in <em>A. acuminata</em> was higher (2.6 ± 0.0001 Mg ha<sup>-1</sup> yr<sup>-1</sup>) that <em>T. micrantha</em> (2.02 ± 0.00001 Mg ha<sup>-1</sup> yr<sup>-1</sup>) (<em>P</em> &lt; 0.001).</p><strong>Conclusions</strong>: Plantations with native species of early succession represent a viable complementary strategy in MCF restoration actions, as well as being carbon sinks that could be contributing to the mitigation of climate change.

<p>Species composition, diversity, structure and microclimate were compared in two edge type of montane cloud forest (FF, edges with pine forest and FS, secondary shrubland) within a forest-edge-exterior gradient at Sierra de Manantlán Biosphere Reserve (Jalisco, Mexico). The cloud forest presented higher richness (126 species, 52 interior habitat specifi c) than pine forests (84) and shrublands (71). Richness and diversity were similar in FF, but species replacement was higher in FS. Density, diameter structure, basal area and canopy cover were major in FF than in FS. Microclimatic and soil condition, was gradual in FF edges and abrupt in FS edges. Tree species of the cloud forests (high density of seedlings and saplings &lt;5 cm diameter breast height) are colonizing the understory of adjacent pine forests, whereas in shrublands their establishment appears to be limited by competition with shrubs and herbaceous species and microclimatic conditions. Our results highlight the importance of considering edge type contrast in conservation and restoration of cloud forest in forest landscapes.</p>

In this paper we describe the structure, floristic composition and woody (tree and shrub) species diversity of a cloud forest at Cuzalapa, Sierra de Manantlán, Jalisco. Two localities with four 2,500 m2 plots each were established at El Durazno and La Pareja. All species present in the plots were identified and recorded, and their diameters at breast height (DBH ≥ 3cm) and heights measured. Forest structure is described using the relative values of density and basal area; in addition, a diagram  of forest profile was drawn for each plot. Among-plot similarity was assessed with Sørensen 's Index. Species diversity was evaluated using Shannon-Wiener 's, Simpson's, and Fisher's α indexes. In the total sampled area (2 ha) 2,086 individuals  belonging to 101 species (including two new records for the flora de la Sierra de Manantlán, Sapranthus foetidus and AIchornea  latifolia), distributed in 75 genera and 44 farnilies, were recorded. The families with the largest numbers of species were:  Leguminosae (8), Solanaceae and Fagaceae (7 each), Moraceae and Compositae (6 each), Lauraceae (5), and Rubiaceae (3).  Tree density at El Durazno and La Pareja was 1,084 and 1,002 trees ha-', and basal area was 38.7 and 31.9 m2 ha-', respectively.  At both localities, Styrax radians had the highest relative importance value. Forest structure and species composition at both  localities correspond to tracks of transitional forest between early to intermediate stages, which results from recurrent anthro- pogenic disturbances such as logging 50 years ago. Species diversity in Cuzalapa is one of the highest ever recorded for cloud  forests of Mexico, which presumably is a consequence of anthropogenic and natural disturbances. Both kind of disturbances  are important forces in maintaining the structure, species composition, and high species diversity in this cloud forest.

Anthropogenic emissions of carbon dioxide are causing unmeasurable damage to our planet. As well as rapidly decreasing annual carbon emissions we need to remove already-emitted carbon dioxide from the atmosphere, so-called negative emissions. However, public opinion is important when deploying new carbon capture technology and prior research has shown that it is more likely to be accepted when local residents have been introduced prior. In this paper we describe a new outreach activity, Recycling Carbon, to introduce the general public to negative emissions technologies. Recycling Carbon was designed by researchers active in the development of carbon capture and utilisation and has proven very versatile, appealing to audiences of 5-75 year olds in a number of settings including classrooms, science fairs and as a public science lecture. Preliminary feedback, in the form of a before-activity and post-activity questionnaire, indicates that engagement with Recycling Carbon improves people’s understanding of negative emissions technology. Finally the paper discusses how engagement with Recycling Carbon is also an opportunity to discuss an individual’s carbon footprint. <br>

Topographic Heterogeneity

We analyzed vegetation structure in a 1-ha plot of cloud forest at Santo Tomás Teipan (Oaxaca, Mexico). Considering its marginal location near the edge of a region covered by this vegetation type on the Sierra Madre del Sur, we examined to what extent this community differed from other cloud forest communities thriving under better conditions for this plant formation. Each individual with diameter at breast height (DBH) ≥2.5 cm was located in a system of coordinates; besides, its taxonomic identity, crown cover, DBH and total height as well as the height to the first branch and the crown base were recorded. Basal area (46.41 m2 ha-1), cover (44,247.33 m2 ha-1), and density (1,035 ind. ha-1) figures fall within the known range for the lower montane rain forests of tropical America. According to structure and composition, two strata were differentiated: a lower one (2 to 11 m), and an upper one (11 to 30 m). Overall dominance corresponded to Cornus disciflora, an upper stratum species. In the plot two topographic conditions were distinguished, namely lower ravine slope and hilltop, which seem to be associated to contrasting soil characteristics. Although this topographic heterogeneity does not match the structural homogeneity of the forest, we detected some clumped patterns for individual species that were preferentially distributed in one of these conditions. The structure of the forest at Teipan is comparable to that of similar forests, but its diversity is relatively low. This may be explained by the absence of taxa occurring in the adjacent dry tropical communities, unlike other cloud forests whose flora appears to be enriched with some elements typical of tropical moist communities with which they abut.
