  abstract = {{B}ackground {S}cots pine ({P}inus sylvestris {L}.) underwent significant population declines across much of northwest {E}urope during the mid-to-late {H}olocene and was thought to have become extirpated in {I}reland from about 400 {AD}. {H}owever, most extant populations are plantations reintroduced from {S}cotland. {O}thers are naturalised therefrom and one in {W}estern {I}reland is a putative relict. {I}n this paper, {S}cots pine in {I}reland are genetically described for the first time. {R}esults {U}sing two mitochondrial (mt{DNA}) loci, eight chloroplast (cp{SSR}) and 18 nuclear (n{SSR}) loci, the genetic composition and diversity of 19 {I}rish {S}cots pine populations is described and compared to other {E}uropean populations. {A}ll trees sampled in {I}reland were fixed for mitotype a, which is the most common across northwest {E}urope. {B}y contrast, cp{SSR} ({H}-{CP} = 0.967) and n{SSR} ({H}-e = 0.540) variation was high, and comparable with estimates for other regions across the species range. {D}ifferentiation at both sets of loci were similarly low (cp{SSR} {F}-{ST} = 0.019; n{SSR} {F}-{ST} = 0.018), but populations from continental {E}urope were significantly differentiated from all {I}rish populations based on n{SSR} variation. {C}onclusions {A}ll {I}rish {S}cots pine are likely part of a common {I}rish-{S}cottish gene pool which diverged from continental {S}cots pine following post-glacial recolonisation. {A} high genetic diversity and an absence of evidence of inbreeding suggests the regional decline of {S}cots pine did not critically reduce allelic variation. {T}he post-glacial relationship between {I}rish and {S}cottish pine is discussed, and a suggestion from recent palaeoecological work that reintroduced {S}cots pine be managed as a native species is now further supported by genetic data.},
