they remain closed until opened by the heat of a forest fire; the abundant seeds are then discharged to regenerate the burned forest. American Forests, Autumn 1999, page 14. The collected cones are heated and tumbled to release the seeds. The flexible leaves (needles) are held in threes, as are the richly-coloured cones, which are serotinous, only opening to release seeds when triggered by the heat of forest fires. Earle, 2014.01.18].

Wilks) Centre: A combination of radiata pine plantations, other introduced trees, native areas and farmingSustainable management of Pinus radiata plantations by bianta はグアダルーペ島 (英語: Guadalupe island、スペイン語: Isla Guadalupe) とセドロス島 (英語:Cedros Island、スペイン語: Isla Cedros) に分布していることが確認されている。これらの島は基変種の分布する南限カリフォルニア州 Cambria からそれぞれ約750 km、約900 kmも離れた太平洋上の小島である[6]。, 本種の生育する地域の気候は太平洋を流れる寒流 (カリフォルニア海流)の影響を強く受けており、湿度が高く、気温は低く、夏には霧が発生する。生息地の一つカリフォルニア州 Monterey の湿度が最低になるのは7月であるが、その時でも平均で60-70%であり湿度は高い[7]。霧は年間の1/3以上の日に発生する[8]。, 気温の変動は全体的に少ない。とは言っても細かく見れば……5℃から40℃まで幅がある。月平均気温で比べてみると、最も寒い月と最も暑い月で比べてみるとその差は約7℃であり、寒暖の差は少ないと言える。具体的には冬の平均気温が9℃から11℃、夏の平均気温が16℃から18℃である。成長期に当たる2月から6月の平均気温は11℃から16℃で、最高気温は17℃から24℃である[9]。霜の降りない期間は年間約300日である。, 年間降水量は約400 - 900 mmであり、年によって変動する。このうち、12月から3月までに300 - 500 mmの降水があるが、残りの時期は月平均50 mmにも満たない。特に7月と8月は雨が降らないことが多い。降水による水分が期待できない季節、樹木は海から内陸へと移動してきた霧を浴びることで、樹冠から水分を吸収している。モントレー半島 (Monterey Peninsula) の高所では霧を浴びることで一週間当たり15 mmの降水量に相当する水分を得ている[10]。雪は原産地においては降らない。アメリカ本土の3か所の分布地を湿度の点で見るとAno Nuevoは最も降水量が多く、Monterey は最も霧が多い、Cambria は最も乾燥している[11]。原産地付近での風は弱く、年間平均で2 m/s程度である。5月は最も風が強く、8月がもっとも弱い[7]。, グアダルーペ島とセドロス島の気候は地中海性気候が色濃く出ており、アメリカ本土よりも雨は少なく気温の変動は極端である。どちらの島でも分布域は霧の影響が強く、マツは霧の切れ間で風上の斜面に生息することが多い。稀に水分の多い深い谷の斜面でも見られる。セドロス島ではマツが生育する場所は霧が最も頻繁に発生し、集中するような場所である[12]。, 原産地における分布域は狭いながらも、生育する土壌は変化に富んでいる。 Ano Nuevo では基岩(underlying rock)は頁岩ないしは海底由来の砂岩 (marine sandstone)である。Monterey においてはこれらに加えて花崗岩も含まれる。Cambria においては石灰岩、砂岩、チャート、粘板岩である。, アメリカ本土のAno Nuevo, Monterey, Cambriaの3か所の地質はいずれもよく似ている。大部分は砂っぽいロームでしばしば海に由来する堆積物である。マツにとって良い場所では有機物の厚い堆積が見られる。有機物の体積は8 - 15 cmの層となることが多く、内部には水や適度の栄養分を含む。このような土壌は斜面で見つかることが多く、水はけが良いのも特徴である。深さ50 - 85 cmのところには粘土層がある。粘土層は とても大切である。マツの根は一般的にこの層よりも下には伸びていかないが、根の多くはこの層を僅かに貫通する。このような根は根と菌類の共生の形態である菌根が形成されている[13]。土壌は一般的に酸性を示し、土層の上部、もしくは粘土層内部は特に酸性が強くなることが多い。粘土の水はけの悪さと酸性の強さが相まって、菌根の形成に良い影響を与えると考えられている。, 本種が好むのは一般的に丘のような地形か緩やかな斜面である。Santa Luica 山脈では例外的に標高300 mの場所に分布しているが、他の場所では海岸と険しい内陸の山岳地帯の間の緩やかな起伏である。アメリカ本土の分布域においてはどの地点でも北斜面に好んで分布することは共通している。他にAno Nuevoでは他のどの方位の斜面にも見られ、Montereyにおいては南向きの狭い谷で見られるが、分布の南限Cambriaでは北側の斜面以外には全く見られなくなる。メキシコの島嶼部ではゆるい所から急なところまで、傾斜の度合いにかかわらず斜面に見られる。標高はグアダルーペ島で300 - 1100 m、セドロス島で270 - 650 mぐらいである[6]。, 分布を制限するものは各地で異なる。Ano Nuevoにおいては海岸に近い場所の浅い土壌が分布を制限する要因と見られる。Montereyにおいては降水量の少なさに加えて、土壌の深さ・構造・粘土層の位置などが分布に影響している。Cambriaにおいては気候と土壌の関係上、高木が成立出来ずに草や低木に移行していくと考えられる。, 化石の記録では、更新世後期には現在よりも広い範囲に分布していたことがうかがえる。この時代は氷期であり海岸線は今よりも後退していた。現在は海中となるような場所や現在は島となっているような場所、具体的にはTomales Bay, Littele Sur, Carpinteria, Rancho La Brea, and Santa Cruz Islandで化石が発見されている[14]。, 本種は天然分布が狭いだけでなく、アメリカでは林業用樹種としてもほとんど使われていない。1960年代の資料によれば、アメリカ本土における分布面積は推定で4,900 haから6,500 ha程度であるとみられている[15]。しかし、その後の変動、特に増加が顕著であるためにこの値は今では当てにならない。たとえば、Ano Nuevo近郊では1970年代に95ha増加している[16]。これは植林したことによっての増加である。しかし、そのような増加を含めても、メキシコの島を合わせた全ての面積は8,000 haに満たないとみられている[6]。, しかし、世界に目を向けると最も植林されているマツ[17]という面白い特徴を持つ。生長の早さ、質の良いパルプが取れるのみでなく、木材としても十分使える品質が評価されてオーストラリア、ニュージーランド、スペインなどでは外来樹種としては最も植えられている[9]。アルゼンチン、チリ、ウルグアイ、ケニアと南アフリカにおいても主要な扱いを受けている。これらの国では自国で使うばかりでなく、輸出して外貨を獲得することも行われるし、天然林の伐採を減らすことも期待されている。ただし、日本では植えられていることは稀である。公園や植物園で生体を見かけることはほとんどない。, 逃げ出した個体が野生化し問題を引き起こしている例も知られている。ニュージーランドでは本種およびコントルタマツ (Pinus contorta)、ベイマツ (Pseudotsuga menzeisii)を中心とした外来樹木の野生化が問題になっている。これら外来種の野生化は生物多様性、主要産業でもある牧畜、土地の価値に悪影響をもたらすことなどが懸念されており、行政機関やボランティアによる抜き取り・枯殺処理が行われている。, 樹高は10 - 40 m程度であり産地や条件で変動するが、基変種 radiata の場合は大抵は20 - 30 m程度、小さいと10 m、大きいと40 m近くになる。樹高の高い個体は小さな渓谷で見つかることが多い。胸高直径は大きく変動し条件の良い場所では60 cmを超える。120 cmを超える巨大なものも稀に見られる。グアダルーペ島において最も高い個体は樹高33 m、胸高直径が最も太いものは211 cmの記録がある。セドロス島では最も高い個体は樹高32 m、胸高直径が大きいのは77 cmであった[6]。, 枝は被圧[注釈 1]されると枯れてしまうものの、幹から離れにくいために枯れ枝を多く付けたままとなる。密集地では枝を出しにくく、枝の無い綺麗な幹になる[8]。成木の樹皮は鱗状に大きく裂ける。, 針葉は基変種では8 - 15 cmのもの3本が束生するが、変種 bianta では2枚が束生する。, 樹冠の発達は樹齢と空間に関係がある。混んでいる場所では小さな樹冠を付ける。旺盛に生長している個体では樹冠が平坦で歪になった後も、樹齢35年から45年程度まで成長を続ける。胸高直径が30 - 45 cmの個体では幅5、6 mの樹冠になるが、混んでいる場所ではもっと小さくなる。胸高直径75 cmの個体の樹冠は幅9 - 12 mであった。30 mを超すような巨木であっても生きている枝を付けている部分の幅は樹高の1/3から1/6しかない[7]。, 原産地においては晩冬から早春に開花する。本種は他のマツ同様に雌雄同株であり、1つの株が雄蕊のみを持つ雄花、雌蕊のみを持つ雌花の2種類の花をつける。たくさんの雄花が枝の脇に、雌花は枝の先端部に形成されるが、雌花はまれに2年生の枝にも形成されることが見られる[18]。, 性成熟するのは樹齢が5年生から10年生の時期であるが、たとえ開けた条件の良い場所で育てても実際には15年生から20年生になるまで実をつけない。密集した場所ではさらに遅くなる。球果が熟すのは2年目の秋で、翌年の早春の暖かい日に鱗片を開き中の種子を散布する。熟した球果は明るい茶色で長さは8 - 18 cm、中に入っている種子は楕円形で艶のある黒色で小さく平均2 cmである。Cambria産の個体は最も大きな球果と種を付け、Monterey産のそれらは最も小さい[2]。1つの球果には120粒から200粒の種子がはいっている。, 球果は熟しても枝からは落ちにくく、長期間枝に付着したままで開閉を繰り返す。他のマツ同様、暖かく乾燥していると開いて中の種子を散布する。熱と乾燥を同時にもたらす火災が起こると、多数の球果が開き、中に入っていた多数の種子が散布される。 Thesis (M.S.

Apical bud in winter; Point Lobos [C.J. radiata について産地別に枝、針葉や球果を多数集めたところ、Cambria の個体群は変種とまではいかないものの他の2つの生息地と違う傾向が見られた。オーストラリアの研究ではこれらの形態・表現型的な違いに加えて遅い成長率、季節ごとの成長に違いが見出されており、おそらく遺伝子的に他の個体群と異なるとされている[2]。近年の研究では各生息地間に僅かな遺伝子的な差異が認められた。そのほとんどは生息地に固有のものだという[3]。, 本種とPinus attenuata やビショップマツ (Pinus muricata) との間で大きく遺伝子移入があるという証拠はないが、雑種の出現は地域的にしか見られない[2]。, 学名Pinus radiata の種小名 radiata は英語のradial(放射状) に由来し、毬果の鱗片の特徴に基づいて名付けられた。英名として一般的な Montrey Pine は本種が広く分布するカリフォルニア州の半島の名前に由来する。他の名前としてはスペイン語風の pino insignis や 種小名 radiata からRadiata pineと呼ばれることも多い。種小名由来の名称は世界的によく使われる。, 日本でもMonterey Pineを直訳したモントレーマツが標準和名として与えられているが、種小名に由来するラジアタマツ、ラジアータマツ、ラジアータパインなどと呼ばれることも多い。ラディアタと表記されることもある。木材の輸入先として大きなニュージーランドやチリを頭に付けたニュージーランドマツやチリーマツという表記も木材・建築業界など、一部で使われているようである[4]。, 基変種、変種ともに自生地は非常に限られている。 基変種はアメリカ合衆国西部カリフォルニア州セントラルコースト (Central coast) の互いに隔絶した3地点、サンマテオ郡 (San Mateo), サンタクルーズ郡 (Santa Cruz), サンルイスオビスポ郡 (San Luis Obispo) で確認されている。この3地点の中で最も北にある場所はAno Nuevoの東側である。同様に真ん中の場所はMonterey や Carmel から約50 km南に行ったところである。一番南の場所は Pico Creek Cambria 地域から約100 km離れている[5]。一番北の場所から一番南の場所までは約200 km離れている。いずれの場所でも海岸に比較的近い場所に生えており、海岸から10 km以上離れた内陸に場所に生えていることはほとんどない。本項では以下、これらカリフォルニアの3地点について近隣の名前をとり、Ano Nuevo(最も北の地点)、Monterey(真ん中の地点)、Cambria(最も南の地点)と記す。, 変種 P. radiata var.
