Information provided in the field 2.8.2: Reported additionnal information: ||
->Range: Short-term trend was derived by comparing data from the 2015-2018 Rare Plants Monitoring Survey [RPMS] (Ní Dhúill et al., in prep.) in the current monitoring period with data from the 2007-2012 survey period (Ní Dhúill et al., 2015), along with data from PhD research into the Irish V. speciosa populations (Ní Dhúill, 2014) and historical records held by NPWS. The period over which the surface area of the species was determined dates from 1960 to 2018. This includes all additional records made during the RPMS, and records from NPWS staff, contractors and other individuals who provided records since the last reporting period.
Favourable Reference Range is set as approximately equal to the current range (10,100 km2).
Since the last reporting period, the range of this species has increased from 7,000 km2 to 10,100 km2 (a 44% increase).
Short-term trend in Range was deemed to be stable. The increase in population and colony numbers is due to improved knowledge and more accurate data rather than expansion of newly established populations. In the reporting period 2007-2012, 64 populations were reported. Since that time, this number has reduced by two: a) one pre-1960 population (Poisoned Glen, Co. Donegal) was erroneously included in the current range in the previous assessment; this population has not been recorded since 1960, is considered to be extinct and is here excluded from the current range; b) the second population forms a natural part of, and is amalgamated with, population TS12, Co. Kerry. The majority of the 24 new populations recorded during the period 2007-2012 were gametophyte-only (67%). One of the new populations comprises gametophytes with juvenile sporophytes that may be recently established (TS71, Co. Kerry). The gametophyte generation has been observed more frequently in recent times as botanists and ecologists are becoming more aware of this cryptic generation and its identification. See Section 6.17 for additional information on the V. speciosa populations.
There are currently fifty-seven 10 km grid squares (5,700 km2) that have at least one V. speciosa record.
Range is assessed as Favourable as there is no evidence of a decline since the Directive came into force. ||
->Population: 'Individuals' in section 6.2 (a) above refers to 'Mature individuals'.
For the purposes of reporting here the population unit ‘mature individuals’ is used as a proxy for ‘colonies’ – see also Article 17 reporting guidelines (DG Environment, 2017). There are currently 86 known extant V. speciosa populations in Ireland, comprising 35 (41%) gametophyte-only populations, 20 (23%) sporophyte-only populations, 30 (35%) co-occurring generation populations and one (1%) population that has only juvenile sporophytes emerging from gametophytes. Of these 86 populations, 41 were scheduled for monitoring during the current reporting period (Ní Dhúill et al., in prep.); 40 were monitored, while one (TS47, Co. Kerry) was not included as the population was inaccessible due to adverse weather conditions.
Population size was determined based on the number of colonies of both generations. This is considered to be the most suitable population unit for recording V. speciosa as it is difficult to define an individual in this rhizomatous (sporophyte) and filamentous (gametophyte) species. A sporophyte colony may comprise an individual or a number of individuals. A gametophyte colony may comprise an individual or thousands of individuals. Frond numbers can fluctuate on an annual basis, therefore, presence or absence of a colony is a more reliable unit than the number of fronds. However, although frond numbers do naturally fluctuate, the numbers are still useful for the future monitoring of each individual colony. Frond numbers were recorded at each colony following the methods described by Ní Dhúill et al. (in prep.).
As noted above, the most suitable unit for measuring population size was considered to be the colony, which was simply defined as a discrete, i.e. unconnected, “patch” or “plant” (Ratcliffe et al., 1993; Rumsey, 1997). With the sporophyte generation, each colony is usually very obvious, occurring as a discrete patch in a crevice, or on a wall or woodland floor. However, with the gametophyte generation the discrete “patches” are not always obvious – the best unit for defining a gametophyte colony is the niche in which the gametophytes occur, i.e. a particular boulder or crevice, or cave, or section of cliff wall. These may contain numerous patches of gametophytes (Ní Dhúill et al., in prep.).
The 86 populations contain 290 colonies, of which there are 142 where only gametophytes occur, 13 where juveniles emerging from gametophytes occur and 135 where mature sporophytes (either with or without gametophytes) occur. Of these 135 colonies, 60 are sporophyte-only, two are sporophyte-only with juveniles (but no gametophyte observed), 44 are co-existing sporophytes and gametophytes and 29 are co-existing sporophytes and gametophytes, with juveniles emerging from gametophytes.
In the previous reporting period (2007-2012) 177 colonies were recorded. In the current reporting period this number was reduced by 28 through amalgamation of colonies with others and through losses, to leave a total of 149 (2007-2012) historical colonies, which are outlined in full in the supporting document (Ní Dhúill et al., in prep.). As of 2018, the total number of colonies within the 86 populations is 290, of which 141 are new records.
Twelve gametophyte colonies at population TS34 (Co. Galway) were amalgamated into three colonies based on a revised definition of gametophyte colonies (Ní Dhúill et al., in prep.), two sporophyte colonies that had been reported at TS12 (Co. Kerry) were considered to comprise one colony and ten gametophyte colonies at population TS24 (Co. Kerry) were considered to represent a single large gametophyte colony that had already been recorded and monitored (TS24.01.02). A further eight sporophyte colonies were considered to have become extinct at seven different populations, most likely due to natural processes such as substrate movement (Ní Dhúill et al., in prep.). The populations where these colonies are considered extinct still contain other sporophyte colonies (with or without gametophytes), with the exception of population TS51 (Co. Kerry), where only gametophytes were recorded in the current reporting period and the Poisoned Glen, Co. Donegal) which no longer supports any known colony of either generation (see section 5.12 for full details on the extinct status of this population). However, the range of the species in Ireland is not impacted by the loss of these colonies. The presence of gametophytes at all but one of these locations is important for possible sporophytic recruitment under future favourable conditions.
Of the 290 colonies within 86 populations, 198 colonies within 40 populations were monitored during the current RPMS (Ní Dhúill et al., in prep.).
During the last reporting period, juvenile sporophytes were rarely observed within the Irish populations, being recorded in only five of these. During the RPMS, juvenile sporophytes were recorded at 12 populations (= 30% of the 40 monitored populations). The trigger for the development of these juvenile sporophytes from gametophytes is unclear but it may be, at least in part, due to climatic factors.
During the last reporting period, 57% of the 23 populations where sporophytes occurred were fertile. In this current reporting period 37% of the 30 populations where sporophytes occurred were fertile. Fluctuation in fertility is not considered problematic, and likely represents natural turnover of fertile fronds.
In addition to using colonies to determine population size, area of occupancy and maximum area were also used. Forty populations that were visited during the RPMS comprising 198 colonies had their areas measured.
Estimates based on Ní Dhúill et al. (in prep.) and expert judgment estimates for the area of occupancy of combined generation colonies discovered recently tallied to 239 m2 with a maximum area of 695 m2.
The area of occupancy for populations not visited since 1960 to date have been extracted from the 2012 Conservation Assessment. Colony records where there was no information on area have been set a minimum value of 0.22 m2 for sporophyte colonies and 0.12 m2 for gametophyte colonies. The method used to derive the assigned areas is described by Ní Dhúill et al. (in prep.). This has been revised from 1 m2 for either generation assigned in 2007-2012, which, in hindsight, was considered to be excessive.
The area of occupancy for the previous reporting period was 280 m2 with a maximum area of 449 m2. Although there was a significant increase in colony numbers since the last reporting period, the apparent reduction in area of occupancy of 15% does not reflect a significant loss in area, but rather accounts for the accurate measurements of previously un-monitored colonies and the use of the revised assigned areas for colonies. It is therefore due to the use of a different method.
The maximum area of colonies has significantly increased by 55% since 2012 which reflects the significant number of new colonies recorded since the last reporting period (141 colonies).
Population was assessed based on number of colonies present, area of occupancy of both generations, frond types, presence of associated gametophytes, number of living fronds and number of juvenile fronds. Juvenile sporophyte frond numbers are reported separately in the Individual Population Conservation Assessments (Ní Dhúill et al., in prep.) as, when present, these numbers may skew the overall frond numbers at a given colony, as not all juveniles would be expected to survive to reach maturity.
Favourable population size is deemed to be approximately equal to the current number of colonies (290) and area of occupancy (239 m2) with a maximum area of 695 m2. Taking into account the losses of sporophyte colonies (outlined in section 6.17), and the fact that one or both generations of V. speciosa colonies are known to still occur in all but one population (Poisoned Glen, Co. Donegal), the current population size is considered to be large enough to allow the long-term survival of this species. With the wider range of distribution of gametophyte colonies and the historical occurrence of sporophytes at the Poisoned Glen, Co. Donegal population, it is highly likely that gametophytes still to be discovered occur within this site.
Population is considered to have an overall Favourable assessment. ||
->HabInfo: V. speciosa is restricted to damp, shady and humid habitats such as dripping caves, cliffs, crevices and gullies by waterfalls and occurs in both woodland and open upland situations. Although there are many apparently suitable sites around Ireland, especially in the south-west, it is not yet fully understood as to why this species is restricted to particular sites.
The habitat for the species was assessed based on the area and quality of the habitat in which the species occurs. The suitable area of habitat corresponds to the area where populations occur, such as a ravine, an area of woodland, cliff-face or crevice.
Short-term trend was assessed by comparing data from the RPMS (Ní Dhúill et al., in prep.) with data from the 2007-2012 reporting period (Ní Dhúill et al., 2015) along with data from PhD research into the Irish V. speciosa populations (Ní Dhúill, 2014) and historical records held by NPWS and other sources.
The area of occupancy and maximum area figures (239 m2 and 695 m2 respectively – see section 6.4) are based on detailed research, targeted surveys and measurement of colonies conducted since the previous assessment. The maximum area of this species (area of both generations combined) is considered to be the area for the habitat (see section 6.17 for full details).
Area of occupancy measurements for the 198 colonies visited were undertaken between 2009 and 2018 (Ní Dhúill et al., 2015 and Ní Dhúill et al., in prep.). For un-monitored colonies, data on area of occupancy in NPWS rare species files suggest that there have been no losses in the area occupied by these populations in the recent past, with the exception of those outlined in section 6.17. Other than the two sporophyte colonies (TS20.04.01, Co. Limerick; TS22.01.07, Co. Cork) there is no evidence to suggest losses since 2000.
Significant reduction in area of occupancy of three colonies at population TS26, Co. Waterford, were likely caused by substrate movement. The effects of bank slippage in sections of population TS26 is a cause for concern. In at least one case, it is likely that the movement of Prunus laurocerasus is causing instability at a section of these steep banks. Although the Habitat for the Species is assessed as Favourable, the overall assessment of population TS26 is Unfavourable-Inadequate due to a significant reduction in the area of colonies TS26.01.04; 14; 19, and a significant reduction in frond numbers at colonies TS26.01.14; 19.
One colony that was reported previously to have significant area and frond loss (TS01.02.01, Co. Tipperary) is now considered to be recovering. However, this population, which comprises 11 colonies, has an Unfavourable-Inadequate assessment for Habitat for the species in the Individual Conservation Assessment due to failing on the target for canopy cover and shade. Another colony is in danger of being severely impacted due to loss of canopy cover and the effects of a grey fungal attack (TS12.01.01, Co. Kerry). At this population (TS12), which comprises three monitored colonies, there is an Unfavourable-Inadequate assessment for Habitat for the species in the Individual Conservation Assessments due to loss of canopy cover and shade at this specific colony, which were lower than the target for a Favourable assessment.
Recent tree fall at a colony (TS08.01.02, Co. Cork) has exposed the left-hand side of this large sporophyte colony (5 m2) to direct sunlight. As this colony failed the target for canopy cover and shade, the overall population had an Unfavourable-Inadequate assessment for Habitat for the species in the Individual Conservation Assessment.
In addition to assessing canopy cover, shade (shade index) and water source, indicators for assessing the habitat for the species also included the occurrence of vigorous native species or invasive non-native species.
NÍ Dhúill et al. (in prep.) observed that, although there is no evidence to suggest that the extent or quality of the habitat for the species has changed significantly in the recent past for colonies and populations visited, the presence of exotic non-native invasive species at six of the populations (listed in section 8.3) where sporophytes occur is of concern due to the likely impact on the habitat where they occur. Although these exotics recorded at six populations are not currently considered to negatively impact the V. speciosa colonies, and in fact, often provide essential canopy cover, their presence within the habitat, and possible measures to control or manage them, may negatively impact these habitats, which in the long term may negatively impact the V. speciosa populations. However, at present, these are considered to be local issues and are not currently considered a threat at the national level.
Population TS52, Co. Kerry, contains all generations of V. speciosa and occurs in a well-established, privately-owned woodland which was planted as far back as the 1830s with a collection of non-native exotics; these are not considered a threat to the V. speciosa colonies at this location at present, and their spread would be limited to the woodland where they occur.
The RPMS (NÍ Dhúill et al., in prep.) and other recent observations have demonstrated that there is sufficient good quality habitat to support the long-term survival of V. speciosa in Ireland.
Habitat for the species is therefore currently assessed as Favourable, although the presence of non-native invasive species should continue to be monitored in the next reporting period. ||
->Future: Conservation measure ‘CI03 Management, control or eradication of other invasive alien species’ is recommended (section 9.5) and issues surrounding its implementation in habitats containing V. speciosa are highlighted (section 9.6).

Short-term trend direction of Range is assessed as stable.
Current range is equal to Favourable Reference Range.
Conservation status of Range is therefore Favourable.
Future trend of Range is assessed as stable.
Future prospects of Range are therefore good.

Short-term trend direction of Population is assessed as stable. The current number of colonies and maximum area approximately equate to a Favourable population size.
Future trend of Population is assessed as stable.
Future prospects for Population are therefore good.

Short-term trend direction of Habitat for the species is stable.
Future trend of Habitat for the species is assessed as stable. However, the impact of the presence of invasive non-native species at a number of populations should be assessed in future surveys and, although not currently considered a national threat, the impact could become of medium importance at the habitats where they occur.
Future prospects of Habitat for the species are therefore good. ||
->Conclusion: There has been no change in the overall conservation status and conservation trend since the last reporting period. Although there have been changes in population size and range size, the conservation status remains Favourable as in 2013.
Of the 40 populations monitored during the current reporting period (Ní Dhúill et al., in prep.), 40% are sporophyte and gametophyte co-existing, with 28% co-existing generations including juvenile sporophytes, 8% sporophyte-only populations and 25% gametophyte-only populations.
During the current reporting period, juvenile sporophytes were recorded at 30% of the 40 monitored populations. Fertile colonies were recorded at 37% of the monitored populations. The recording of additional juvenile sporophytes is, in part, the result of targeted surveying, improved knowledge and more accurate data, but may also be partly due to climatic factors.
Sporophyte colonies lost at pre-1994 historical sites are unlikely to be restored in the future due to likely irreversible habitat loss (see details of colony losses in section 6.17). Surviving colonies at two populations where there were losses of sporophyte colonies (TS20.04.01, Co. Limerick and TS22.01.07, Co. Cork) since the last reporting period are not considered under particular threat. As there is no other evidence of a decline in population size since the Directive came into force, Population is assessed as Favourable.
Non-native invasive species present at certain locations are considered likely to impact the quality of the habitat; however, no evidence of negative impacts on the species or habitat since the last reporting period have been identified.
The habitat of V. speciosa is largely in good condition, and most identified suitable areas still support V. speciosa. Habitat is assessed as Favourable.
There is the threat posed by the presence of exotic invasive species in some sites for the species (outlined in section 8.3); however, this is considered to be a localised issue at present. The impact of invasive non-native species is difficult to assess at locations where they occur, as discussed in section 9.6. There are no other current pressures significantly impacting the V. speciosa populations. Most populations are within the SAC network (59 of the 86 known populations) and the Flora (Protection) Order, 2015 protects all populations. There are no reasons to believe that significant threats will present themselves in the future, therefore the Future prospects are assessed as Favourable.
Considering the impacts, pressures and threats to V. speciosa in Ireland today and the measures in place that will assist its protection, it is expected that this species will survive. The overall Conservation Status for V. speciosa is Favourable and the overall Conservation Trend is stable. ||

C'est un critère d'évaluation qui n'a aucun intérêt et aucun sens pour une espèce comme Vandenboschia, notamment quand la plante ne s'exprime que par son thalophyte. Elle forme dans ce cas un tapis dense et uniforme à partir duquel il est strictement impossible d'identifier le moindre individu. Pour cette espèce, selon les densités de populations, il semblerait préférable d'utiliser une unité comme le nombre de localité ou la maille de 1x1km.
