Collected Evidence: Collected Evidence: Cover peatland with something other than mulch (without planting) Two studies evaluated the effects, on peatland vegetation, of covering a peatland with something other than mulch (without planting). Both studies were in bogs. Vegetation cover (2 studies): One replicated, controlled, before-and-after study in a bog in Germany reported that covering bare peat with fleece or fibre mats did not affect the number of seedlings of five herb/shrub species. One replicated, controlled, before-and-after study in bogs in Australia reported that recently-burned plots shaded with plastic mesh developed greater cover of native plants, forbs and Sphagnum moss than unshaded plots.

The study was in a bog. Vegetation cover (1 study): One controlled, before-and-after study in a bog in the UK found that pegging coconut fibre rolls onto almost-bare peat did not affect the development of vegetation cover (total, mosses, shrubs or cottongrasses).

The study was in a tropical peat swamp. Vegetation cover (1 study): One replicated, paired, controlled study in a peat swamp forest in Indonesia found that artificial bird perches had no significant effect on seedling abundance. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1817https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1817Tue, 28 Nov 2017 08:44:19 +0000Collected Evidence: Collected Evidence: Directly plant peatland mosses Seven studies evaluated the effects on peatland vegetation of planting mosses. Six studies were in bogs and one was in a fen. Survival (1 study): One study in Lithuania reported that of 50 Sphagnum-dominated sods planted into a rewetted bog, 47 survived for one year. Growth (2 studies): Two before-and-after studies in a fen in the Netherlands and bog pools in the UK reported that mosses grew after planting. Moss cover (5 studies): Five before-and-after studies in a fen in the Netherlands and bogs in Germany, Ireland, Estonia and Australia reported that after planting mosses, the area covered by moss increased in at least some cases. The study in the Netherlands reported spread of planted moss beyond the introduction site. The study in Australia was also controlled and reported that planted plots developed greater Sphagnum moss cover than unplanted plots. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1818https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1818Tue, 28 Nov 2017 08:44:34 +0000Collected Evidence: Collected Evidence: Directly plant peatland herbs Five studies evaluated the effects on peatland vegetation of planting herbaceous plants. Three studies were in fens or fen meadows and two were in bogs. Survival (3 studies): Three replicated studies in a fen meadow in the Netherlands and fens in the USA reported that planted herbs survived over 2–3 years. However, for six of nine species only a minority of individuals survived. Growth (2 studies): Two replicated before-and-after studies in a bog in Germany and fens in the USA reported that individual planted herbs grew. Vegetation cover (1 study): One replicated, controlled, before-and-after study in Canada found that planting herbs had no effect on moss, herb or shrub cover in created bog pools relative to natural colonization. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1819https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1819Tue, 28 Nov 2017 08:44:55 +0000Collected Evidence: Collected Evidence: Directly plant peatland trees/shrubs Eleven studies evaluated the effects, on peatland vegetation, of planting trees/shrubs to restore or create forested/shrubby peatland. Seven studies were in tropical peat swamps, three in bogs and one in a fen. Survival (10 studies): Eight studies (seven replicated) in peat swamp forests in Thailand, Malaysia and Indonesia and bogs in Canada reported that the majority of planted trees/shrubs survived over periods between 10 weeks and 13 years. Species with <50% survival included Dacryodes, poplar and katok. One replicated study in a fen in the USA reported that most planted willow cuttings died within two years. One study in a peat swamp forest in Indonesia reported <5% survival of planted trees after five months, following unusually deep flooding. Growth (5 studies): Four studies (including two replicated, before-and-after) in peat swamp forests in Thailand, Indonesia and Malaysia reported that planted trees grew. One replicated before-and-after study in bogs in Canada reported that planted shrubs grew. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1820https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1820Tue, 28 Nov 2017 08:45:21 +0000Collected Evidence: Collected Evidence: Add mosses to peatland surface Thirteen studies evaluated the effects of adding mosses or moss fragments onto peatland surfaces. Eleven were in bogs and two in were in fens. One study was a continuation of an earlier study. Three of the studies involved sowing moss in gel beads. Sphagnum moss cover (12 studies): Eleven studies in bogs in the UK, Canada, Finland and Germany and fens the USA reported that Sphagnum moss was present, after 1–4 growing seasons, in at least some plots sown with Sphagnum. Cover ranged from negligible to >90%. Six of these studies were controlled and found that Sphagnum cover or abundance was higher in sown than unsown plots. One of the studies reported that Sphagnum only survived in one of three sites, and only when plots were mulched. One additional study in Canada found that adding Sphagnum to bog pools did not affect Sphagnum Other moss cover (4 studies): Four studies (including one replicated, randomized, paired, controlled, before-and-after) in bogs in Canada and fens in Sweden and the USA reported that mosses or bryophytes other than Sphagnum were present, after 2–3 growing seasons, in at least some plots sown with moss fragments. Cover ranged from negligible to 76%. In the fens in Sweden and the USA, moss cover was low (<1%) unless the plots were mulched, shaded or limed. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1821https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1821Tue, 28 Nov 2017 08:45:38 +0000Collected Evidence: Collected Evidence: Add mixed vegetation to peatland surface Eighteen studies evaluated the effects on peatland vegetation of spreading mixed vegetation onto the peatland surface. All 18 studies were in bogs (two being restored as fens). One study was a continuation of an earlier study. Characteristic plants (1 study): One replicated, randomized, paired, controlled, before-and-after study in a degraded bog in Canada found that adding fen vegetation increased the number and cover of fen-characteristic plant species. Sphagnum moss cover (17 studies): Seventeen replicated studies (five also randomized, paired, controlled, before-and-after) in bogs in Canada, the USA and Estonia reported that Sphagnum moss was present, after 1–6 growing seasons, in at least some plots sown with vegetation containing Sphagnum. Cover ranged from <1 to 73%. Six of the studies were controlled and found that Sphagnum cover was higher in sown than unsown plots. Five of the studies reported that Sphagnum cover was very low (<1%) unless plots were mulched after spreading fragments. Other moss cover (8 studies): Eight replicated studies (seven before-and-after, one controlled) in bogs in Canada, the USA and Estonia reported that mosses or bryophytes other than Sphagnum were present, after 1–6 growing seasons, in at least some plots sown with mixed peatland vegetation. Cover was <1–65%. Vascular plant cover (10 studies): Ten replicated studies in Canada, the USA and Estonia reported that vascular plants appeared following addition of mixed vegetation fragments to bogs. Two of the studies were controlled: one found that vascular plant cover was significantly higher in sown than unsown plots, but one found that sowing peatland vegetation did not affect herb cover. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1822https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1822Tue, 28 Nov 2017 08:45:54 +0000Collected Evidence: Collected Evidence: Introduce seeds of peatland herbs Ten studies evaluated the effects, on peatland vegetation, of introducing seeds of herbaceous peatland plants. Seven studies were in fens or fen meadows, two in bogs and one in unspecified peatland. Germination (2 studies): Two replicated studies reported that some planted herb seeds germinated. In a bog in Germany three of four species germinated, but in a fen in the USA only one of seven species germinated. Characteristic plants (3 studies): Three studies (two controlled) in fen meadows in Germany and a peatland in China reported that wetland-characteristic or peatland-characteristic plants colonized plots where herb seeds were sown (sometimes along with other interventions). Herb cover (4 studies): Three before-and-after studies (one also replicated, randomized, paired, controlled) in a bog in New Zealand, fen meadows in Switzerland and a peatland in China reported that plots sown with herb seeds developed cover of the sown herbs (and in New Zealand, greater cover than unsown plots). In China, the effect of sowing was not separated from the effects of other interventions. One replicated, randomized, paired, controlled study in a fen in the USA found that plots sown with herb (and shrub) seeds developed similar herb cover to plots that were not sown. Overall vegetation cover (3 studies): Of three replicated, controlled studies, one in a fen in the USA found that sowing herb (and shrub) seeds increased total vegetation cover. One study in a bog in New Zealand found that sowing herb seeds had no effect on total vegetation cover. One study in a fen meadow in Poland found that the effect of adding seed-rich hay depended on other treatments applied to plots. Overall plant richness/diversity (4 studies): Two replicated, controlled studies in fens in the USA and Poland found that sowing herb seeds had no effect on plant species richness (total or vascular). Two replicated, controlled, before-and-after studies in a bog in New Zealand and a fen meadow in Poland each reported inconsistent effects of herb sowing on total plant species richness. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1823https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1823Tue, 28 Nov 2017 08:46:08 +0000Collected Evidence: Collected Evidence: Introduce seeds of peatland trees/shrubs Five studies evaluated the effects, on peatland vegetation, of introducing seeds of peatland trees/shrubs to restore or create forested/shrubby peatland. Three studies were in bogs and two were in fens. Germination (2 studies): Two replicated studies in a bog in Germany and a fen in the USA reported germination of heather and willow seeds, respectively, in at least some sown plots. Survival (2 studies): One replicated study in a bog in Germany reported survival of some heather seedlings over two years. One replicated study in a fen in the USA reported that all germinated willow seedlings died within one month. Shrub cover (3 studies): Two studies (one replicated, randomized, paired, controlled) in bogs in New Zealand and Estonia reported that plots sown with shrub seeds (sometimes along with other interventions) developed greater cover of some shrubs than plots that were not sown: sown manuka or naturally colonizing heather (but not sown cranberry). One replicated, randomized, paired, controlled study in a fen in the USA found that plots sown with shrub (and herb) seeds developed similar overall shrub cover to unsown plots within two years. Overall vegetation cover (3 studies): Two replicated, randomized, paired, controlled studies in a bog in New Zealand and a fen in the USA reported that plots sown with shrub (and herb) seeds developed greater total vegetation cover than unsown plots after two years. One site comparison study in bogs in Estonia reported that sowing shrub seeds (along with fertilization) had no effect on total vegetation cover after 25 years. Overall plant richness/diversity (3 studies): One site comparison study in bogs in Estonia reported that sowing shrub seeds (along with fertilization) increased plant species richness. However, one replicated, randomized, paired, controlled study in a bog in New Zealand reported that plots sown with shrub seeds typically contained fewer plant species than plots that were not sown. One replicated, randomized, paired, controlled study in a fen in the USA found that sowing shrub (and herb) seeds had no effect on plant species richness. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1824https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1824Tue, 28 Nov 2017 08:46:23 +0000Collected Evidence: Collected Evidence: Add lime (before/after planting) Six studies evaluated the effects on peatland vegetation of liming areas planted with peatland plants. Four studies involved fen plants, one involved bog plants and one involved peat swamp plants. Two of the studies were in greenhouses/nurseries. Survival (2 studies): One replicated, controlled study in the Netherlands reported that liming typically reduced survival of planted fen herbs after two growing seasons. One replicated, randomized, paired, controlled study in Sweden found that liming increased survival of planted fen mosses over one growing season. Growth (3 studies): Two controlled, before-and-after studies found that liming did not increase growth of planted peatland vegetation. Liming reduced or had no effect on Sphagnum moss growth in bog pools in the UK, and reduced growth rates for the majority of peat swamp tree seedlings in a nursery in Indonesia. One replicated, controlled, before-and-after study in Sweden found that liming increased growth of planted fen mosses. Cover (2 studies): One replicated, randomized, paired, controlled, before-and-after study in a fen in Sweden found that liming increased cover of sown mosses. However, one replicated, randomized, paired, controlled study in a bog in Canada found that liming plots sown with fen vegetation fragments had no effect on total vegetation, vascular plant or bryophyte cover.

Eight studies were in bogs (two being restored as fens). One study was in a tropical peat swamp nursery. Survival (2 studies): Two replicated, randomized, paired, controlled studies in bogs in Canada examined the effect, on plant survival, of adding inorganic fertilizer to areas planted with peatland plants. One study reported that fertilizer increased survival of two planted tree species. The other study found that fertilizer had no effect on three planted tree species and reduced survival of one. Growth (6 studies): Five studies (three replicated, randomized, paired, controlled) in bogs in the UK, Germany and Canada found that fertilizer typically increased growth of planted mosses, herbs or trees. However, for some species or in some conditions, fertilizer had no effect on growth. One replicated, randomized, controlled, before-and-after study in a nursery in Indonesia found that fertilizer typically had no effect on growth of peat swamp tree seedlings. Cover (3 studies): Three replicated, randomized, paired, controlled studies examined the effect, on vegetation cover, of fertilizing areas planted with peatland plants. One study in a bog in Canada found that fertilizer increased total vegetation, vascular plant and bryophyte cover. Another study in a bog (being restored as a fen) in Canada found that fertilizer increased sedge cover but had no effect on total vegetation cover, total herb cover or Sphagnum moss cover. One study in a bog in New Zealand reported that fertilizer typically increased cover of a sown shrub and rush, but this depended on the chemical in the fertilizer and preparation of the peat.

Nine studies were in bogs (one being restored as a fen). Two studies were in fens. One was in a tropical peat swamp. Germination (1 study): One replicated, controlled, before-and-after study in a bog in Germany found that mulching after sowing seeds increased germination rates for two species (a grass and a shrub), but had no effect on three other herb species. Survival (3 studies): Two replicated, paired, controlled studies in a fen in Sweden and a bog in the USA reported that mulching increased survival of planted vegetation (mosses or sedges). One replicated, paired, controlled study in Indonesia reported that mulching with oil palm fruits reduced survival of planted peat swamp tree seedlings. Growth (1 study): One replicated, randomized, paired, controlled, before-and-after study in a fen in the USA reported that mulching increased growth of transplanted sedges. Cover (9 studies): Six studies (including four replicated, randomized, paired, controlled, before-and-after) in bogs in Canada and the USA and a fen in Sweden found that mulching after planting increased vegetation cover (specifically total vegetation, total mosses/bryophytes, Sphagnum mosses or vascular plants after 1–3 growing seasons). Three replicated, randomized, paired, controlled, before-and-after studies in degraded bogs in Canada found that mulching after planting had no effect on vegetation cover (Sphagnum mosses or fen-characteristic plants).

Five studies involved bog plants, two involved fen plants and one involved peat swamp plants. Two of the studies were in greenhouses or nurseries. Germination (1 study): One replicated, controlled, before-and-after study in a bog in Germany reported mixed effects of fleece and fibre mats on germination of sown herb and shrub seeds (positive or no effect, depending on species). Survival (2 studies): Two replicated, randomized, controlled studies examined the effect, on plant survival, of covering planted areas. One study in a fen in Sweden reported that shading with plastic mesh increased survival of planted mosses. One study in a nursery in Indonesia reported that shading with plastic mesh typically had no effect on survival of peat swamp tree species, but increased survival of some. Growth (3 studies): Three replicated, randomized, controlled, before-and-after studies examined the effect, on plant growth, of covering planted areas. One study in a greenhouse in Switzerland found that covering planted Sphagnum mosses with transparent plastic sheets or shading mesh increased their growth. One study in a fen in Sweden found that shading with plastic mesh reduced growth of planted fen mosses. One study in a nursery in Indonesia reported that seedlings shaded with plastic mesh grew taller and thinner than unshaded seedlings. Cover (4 studies): Two replicated, paired studies in a fen in Sweden and a bog in Australia reported that shading plots with plastic mesh increased cover of planted mosses. One study in a bog in Canada found that covering sown plots with plastic mesh, not transparent plastic sheets, increased the number of Sphagnum moss shoots. Another study in a bog in Canada reported that shading sown plots with plastic mesh had no effect on cover of vegetation overall, vascular plants, Sphagnum or other moss.

Two studies were in bogs. One was in a tropical peat swamp. Survival (1 study): One replicated, paired, controlled study in Malaysia reported that planting nurse trees had no effect on survival of planted peat swamp tree seedlings (six species). Cover (2 studies): Two replicated, randomized, paired, controlled, before-and-after studies in bogs in the USA and Canada found that planting nurse herbs had no effect on cover, after 2–3 years, of other planted vegetation (mosses/bryophytes, vascular plants or total cover).

The study was in a bog. Cover (1 study): One replicated, paired, controlled, before-and-after study in a bog in Canada found that irrigation increased the number of Sphagnum moss shoots present 1–2 growing seasons after sowing Sphagnum fragments. Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1832https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F1832Tue, 28 Nov 2017 08:52:45 +0000Collected Evidence: Collected Evidence: Reprofile/relandscape peatland (before planting) Four studies evaluated the effects, on peatland vegetation, of reprofiling or relandscaping before planting peatland plants. All four studies were in bogs. Survival (1 study): One replicated, paired, controlled study in a bog in Canada found that survival of sown Sphagnum mosses was higher, after one growing season, in reprofiled basins than on raised plots. Cover (3 studies): Two replicated, controlled, before-and-after studies in bogs in Canada found that reprofiled basins had higher Sphagnum cover than raised plots, 3–4 growing seasons after sowing Sphagnum-dominated vegetation fragments. However, one controlled study in a bog in Estonia reported that total Sphagnum cover did not differ between reprofiled and raised plots, 1–2 years after sowing. All three studies found that reprofiled and raised plots developed similar cover of other mosses/bryophytes and vascular plants.

Two studies were in bogs. One was in a tropical peat swamp. Growth (1 study): One controlled study in a peat swamp in Thailand reported that trees planted into mounds of peat grew thicker stems than trees planted at ground level. Cover (2 studies): Two replicated, randomized, paired, controlled, before-and-after studies in bogs in Canada found that roughening the peat surface (by harrowing, ploughing, creating vehicle tracks or adding peat blocks) did not significantly affect cover of planted Sphagnum moss after 1–3 growing seasons.

The study was in a bog. Cover (1 study): One replicated, controlled, before-and-after study in a bog New Zealand reported that plots amended with fine peat supported higher cover of two sown plant species than the original (tilled) bog surface. However, for one species fertilization cancelled out this effect.
